Should I use rename or soemthing?

Yes you can try this.

import os
import fnmatch

for i,fn in enumerate(os.listdir("C:/Bilder")):
    if fnmatch.fnmatch(fn, 'IMG*'):
        os.rename(os.path.join('C:/Bilder', fn), os.path.join('C:/Bilder','Bilde%d.jpg' % i))

What is the full name,and what should the new full name be?,you most explain better.
IMG.jpg to HH.jpg?
HH1.jpg HH2.jpg....?

import os
os.chdir('D:/Python24/pyasn1')
python setup.py install

This is wrong.
Do you know what cmd is?
http://www.bleepingcomputer.com/tutorials/tutorial76.html
When you have unpacked files you need to navigate to that folder in cmd.
Then use python setup.py install .
This is one way.

The other are using setuptools as postet before.
It took my 15sek to install pysnmp with setuptools.
This is also done in cmd and not in IDLE easy_install pysnmp

#!/usr/bin/env python

This is only for linux,on windows you dont need that line.

From CMD. easy_install pysnmp .
To do this you need to install Setuptools
Or as Gribouillis posted from CMD navigate to folder for unpack files and write python setup.py install

>>> import pysnmp
>>> dir(pysnmp)
['__builtins__',
 '__doc__',
 '__file__',
 '__loader__',
 '__name__',
 '__package__',
 '__path__',
 'majorVersionId',
 'version']
>>> pysnmp.version
(4, 1, 15)
>>>

>>> l = ['asd',"asd'das",'qw','213']
>>> l
['asd', "asd'das", 'qw', '213']
>>> l.pop(0)
'asd'
>>> l
["asd'das", 'qw', '213']
>>> l.pop(1)
'qw'
>>> l
["asd'das", '213']
>>>

This is what`s happens.
l.pop(0) take out take out 'asd'
Then "asd'das" take place as element 0
Next when you use l.pop(1) it will take our element 1 'qw'
Maybe you get confused that "asd'das" is one element in the list.

You are looking for random.shuffle().
To see all method under random module use dir(random)
For help use help(random.shuffle)

>>> random_name = ['Mohamed', 'Ahmed','Aboubakr']
>>> random.shuffle(random_name)
>>> random_name
['Mohamed', 'Aboubakr', 'Ahmed']
>>> random.shuffle(random_name)
>>> random_name
['Ahmed', 'Mohamed', 'Aboubakr']
>>> random.shuffle(random_name)
>>> random_name
['Ahmed', 'Aboubakr', 'Mohamed']
>>>

Any idea how to change the format to something like this?

You can use the new string formatting has a lot of powerful features an was new in python 2.6
http://docs.python.org/library/string.html#formatstrings
An example.

google = {
    'facebook.com': 230,
    'yahoo.com': 9,
    'fifa.org': 67,
    'msn.com': 3}

print 'google.com'
for name in sorted(google):
    print("\t\t{name:11}{score:>10.4f}".format(name=name, score=google[name]))

"""Out-->
google.com
	facebook.com  230.0000
	fifa.org      67.0000
	msn.com        3.0000
	yahoo.com      9.0000

i m using python 2.5 ,i m getting error in the first line(i.e,with open line)

Why are using an so old version as 2.5?.
I shall test later on my laptop there i have 2.5 and see if it work.
The with statement did come with the release of python 2.5.
http://docs.python.org/whatsnew/2.5.html#pep-343-the-with-statement
You can try to add this as first line.
from __future__ import with_statement

Write this in IDLE.

>>> import sys
>>> sys.path

The list you get is where python look for .py files,when you are using a import statment.
http://docs.python.org/tutorial/modules.html#the-module-search-path

Dont use bold character for everthing.
Here is and example you can look at and try out.

#average.py
#saved in python dir
from __future__ import division

def average(seq_in):
    if isinstance(seq_in, (list, tuple)):
        return sum(seq_in) / len(seq_in)
    else:
        return 'Input can only be list or tuple'

So we save this as average.py in python folder(or a python path folder so python can find it)
Import and test it out before we use it in new script.

>>> from average import average
>>> average
<function average at 0x04D2C430>
>>> average([1,2,3,4])
2.5
>>> average(88)
'Input can only be list or tuple'
>>> average('hi')
'Input can only be list or tuple'
>>>

It work as it should.
Then we can use it in a new code like this.

from average import average

def calc_average(l):
       return average(l) #Here we use the imported code

def radius_2():
    '''Not finish yet'''
    pass

def main():
    '''Main menu'''
    while True:
        print '(1) Calculate average'
        print '(2) Calculate radius'
        print '(Q) Quit'
        choice = raw_input('Enter your choice: ')
        if choice == '1':
            user_in = raw_input('Enter numbers for average calculation: ')
            a = [float(i) for i in user_in]
            print calc_average(a)
        elif choice == '2':
            radius_2()
        elif choice in ['Q','q']:
            return False
        else:
            print 'Not a correct choice:', choice

Use code tag,are you using python 3?
Then you have to change print statement,because as mention many times print is a function in python 3.

i agree with the splicing which i've found helpful.

"splicing" is that a secret python slicing method,just kidding :icon_wink:
"splicing" in action.

Or.

Read this.

The array module is kind of one of those things that you probably don't have a need for if you don't know why you would use it (and take note that I'm not trying to say that in a condescending manner!). Most of the time, the array module is used to interface with C code.

Use list as i have canged in your code.
sum(list/tuple) not list/tuple.sum.

#The normal way off making list/array in python
homescore = []
visitingscore = []

for x in range(2):
    home = int(raw_input('The home team score this inning. '))
    homescore.append(home)

for x in range(2):
    visiter = int(raw_input('The visiting team score this inning. '))
    visitingscore.append(visiter)

print 'The Home team score is ', sum(homescore)
print 'The Visiters team score is %d ' % sum(visitingscore) #with string formatting

if sum(homescore) > sum(visitingscore):
    print"The Home team wins!"
else:
    print"The visiting team wins!"

now i can't figure out what does find+1 means..

A clue most programming start indexing/counting at 0.

def find_genes(gene,sequence):
    my_list= []  #Dont use list as a varible name,it`s a python keyword

    count = sequence.count(gene)
    find = sequence.find(gene)
    my_list.append(find)

    while find > -1:
        find = sequence.find(gene,find+1)
        my_list.append(find)
        return count,my_list  #Move to remove -1

text = """\
My name is Fred Flintstone and I am a famous TV
star.I have as much authority as the Pope,I
just don't have as many people who believe it.
Fred
"""
gene = 'Fred'

count,index_word =  find_genes(gene,text)
print '%s occurred %s times,at index %s' % (gene,count,index_word)

It work fine for me,it has no error so it should work for you to.
In your first code both __int__ statement was wrong should be __init__

import wx

class my_window(wx.Frame):
    def __init__(self, parent, id):
        wx.Frame.__init__(self,parent,id,'My Window', size=(300,200))
    
        self.SetBackgroundColour('BLACK')

if __name__ == "__main__":
    app=wx.PySimpleApp()
    frame=my_window(parent=None,id=-1)
    frame.Show()
    app.MainLoop()

import wx

class my_window(wx.Frame):
    def __init__(self, parent, id):  #error __int__
        wx.Frame.__init__(self,parent,id,'My Window', size=(300,200))

        #Panel for frame
        self.panel = wx.Panel(self)
        self.SetBackgroundColour('blue')

if __name__ == "__main__":
    app=wx.PySimpleApp()
    frame=my_window(parent=None,id=-1)
    frame.Show()
    app.MainLoop()

Should not be so hard to understand it`s a slice method that work on string.
your string[start:end]

>>> s = 'my car'
>>> s[0]
'm'
>>> #m is first,we cont from zero

>>> #So if we want to take out car,we count [start:end]
>>> start = 3
>>> end = 6
>>> s[start:end]
'car'
>>>

'''
#part.txt
This is a test.
I want to take out this part,of the text
'''

f = open('part.txt')
#readlines() return a list,so string slice wont work [start:end]
print f.readlines()
#--> ['This is a test.\n', 'I want to take out this part,of the text']


f = open('part.txt')
#read() return a string and you can use string slice
print f.read()[35:44]
#--> this part

#Join() as you may now convert a list to string
''.join(['This is a test.\n', 'I want to take out this part,of the text'])[35:44]
#--> this part

No,i dont get None at the end.

and
the
happy
summer
days
the
end
>>>

read_book(file_in) #ok
print read_book(file_in) #will return None,because you are calling a function that has no return statement

Some advice,and no None as d5ed poinet out.

import string

def read_book(file_in=None):
    '''
    Read in file,strips whitespace-punctuation
    Returns them in lowercase
     '''
    f = open(file_in)  #r is default
    for l in f:        #Dont need readlines
        book_line = l.strip().translate(None, string.punctuation)
        for w in book_line.split(" "):
            if w != "":
                print w.lower()

def main():
    """main function"""
    file_in = 'alice.txt'
    read_book(file_in)  #The function you calling has print
    #return 0           #Not needed in python how has an excellent garbage collection

PyQt is compitable with python 3,and of course build in Tkinter.
http://www.riverbankcomputing.co.uk/news
For beginner there is a massive amount of quality book/tutorials/forum help that are almost all inn pyhon 2.x.
Is not a smart ting to overlook all that info because you look only for for python 3 stuff.

Tentative wxPython Roadmap.
http://wiki.wxpython.org/TentativeRoadmap

PortingDjangoTo3k
http://wiki.python.org/moin/PortingDjangoTo3k

Just have both installed as most of us have.
Wxpyhon is a excellent GUI toolkit use python 2.x if you need to use that.

This topic has been upp several times,python is python dont get hang up in python 2.x or 3.x.
If you are learning python 3.,you are learing python 2.x and visa versa.
Just get ourself uppdatet what the differences are.

Nice one woooee.
Just need a fix of range[1, 6] to range(1, 6)

Not your lucky day snippsat, double post and:

Yes,a misstype when a did some edting of forum code thx.
Did fix it now.

You have to some reading about dictionary.
Some stuff you can look at.

>>> z = {'a': 1, 'a': 2, 'a': 3, 'b': 4, 'c': 5}
>>> z
{'a': 3, 'b': 4, 'c': 5}
>>> #Keys are unique within a dictionary while values may not be
>>> #That`s why only last value 3 is bind to key 'a'

>>> d = {'a' (1,2,3)
>>> d['a']
(1, 2, 3)
>>> #now key 'a' has value of 1,2,3
>>> d.keys()
['a']
>>> d.values()
[(1, 2, 3)]
 
>>>#some explation  about get.
>>>#dict.get(key, default=None)
>>>#For key key, returns value or default if key not in dictionary
>>> z.get('a')
3
>>> d.get('a')
(1, 2, 3)
>>> print d.get('b')
None
>>>

A rule that can be good to remember.
Never delete something from or add something to the list you are iterating over.

The solution is:
Iterate over your original list, and put everything which passes your test into another list.

Some way of doing this.
Using List comprehensions.

>>> l = [1,2,3,4,5,6,7,8]
>>> odd_remove = [item for item in l if item %2 != 1]
>>> odd_remove
[2, 4, 6, 8]
>>>

l = [1,2,3,4,5,6,7,8]

even_list = []
for item in l:
    if item %2 != 1:
        even_list.append(item)

print even_list  #[2, 4, 6, 8]

l = [1,2,3,4,5,6,7,8]

for item in l[:]: #make a copy of list
	if item %2 != 0:
	    l.remove(item)

print l  #[2, 4, 6, 8]

Getters and setters are evil. Evil, evil, I say! Python objects are not Java beans. Do not write getters and setters. This is what the ‘property’ built-in is for. And do not take that to mean that you should write getters and setters, and then wrap them in ‘property’.

http://tomayko.com/writings/getters-setters-fuxors

The link over is follow up from python is Not java.
http://dirtsimple.org/2004/12/python-is-not-java.html

An example i make some code that calulate average.

#average.py
#saved in python dir
from __future__ import division

def average(average_list):
    if isinstance(average_list, (list, tuple)):
        return sum(average_list)/len(average_list)
    else:
        return 'Input can only be list or tuple'

So import it and test it out.
Save it in python sys.path or same folder as your other .py-file.

#Check out path
>>> import sys
>>> sys.path

>>> from average import average
>>> average
<function average at 0x04D2C430>
>>> average([1,2,3,4])
2.5
>>> average(88)
'Input can only be list or tuple'
>>> average('hi')
'Input can only be list or tuple'
>>>

Use code tags.
A shorter way to average.

from __future__ import division

def getAverage(numList):
    return sum(numList)/len(numList)

print getAverage([1,2,3,4])

Some pratice you can try out in IDLE.

>>> name = raw_input("Enter Name: ")
Enter Name: joe
>>> name
'joe'
>>> list(name)
['j', 'o', 'e']

>>> #This is called list comprehension
>>> [i for i in name]
['j', 'o', 'e']

>>> #Written as an ordenarry loop
>>> my_list = []
>>> for i in name:
	my_list.append(i)	
>>> my_list
['j', 'o', 'e']

#one with map()
>>> map(str, name)
['j', 'o', 'e']

>>> #convert to string
>>> ''.join(my_list)
'joe'

>>> n = (1+2+3+4+5+6)
>>> n
21

>>> l = list(str(n))
>>> l
['2', '1']

#list comprehension
>>> [i for i in l]
['2', '1']
>>> [int(i) for i in l]
[2, 1]
>>> sum([int(i) for i in l])
3
>>>

ran it and I was so happy with it, but then... why on Earth does it tell me that "5" is higher than "24"? Or why does it tell me that "5" is higher than "45"?? Or why "5" is higher than "13"?

Because you are comparing string and not integer.
Python 3 has only input() and it return a string,but you can choose what datatype it shall return with int() float() .

Just an advice.
For beginner there is a massive amout of tutorials/books/forum help that are in python 2.x this is important stuff for learing python.
If you learn python 2.x you learn of course python 3.x,have both installed is a good chooice.
Most pepole still use python 2.x in wait for many 3 part moduls to be rewritten in python 3.

#python 3
>>> x = input('Give a value for \'a\': ')
>>> Give a value for 'a': 5
>>> type(x)
<class 'str'>

>>> x = int(input('Give a value for \'a\': '))
>>> >>> Give a value for 'a': 3
>>> type(x)
<class 'int'>

>>> #Or use float for decimal number
>>> x = float(input('Give a value for \'a\': '))
>>> Give a value for 'a': 5.3  
>>> type(x)
<class 'float'>

>>> #You can also convert later in code
>>>  if float(a) > float(b):

>>> Z = []
>>> X=['a']
>>> Y=['b','c','d','e','f']
>>> for i in Y:
...     Z.append(X[0] + i)
...     
>>> Z
['ab', 'ac', 'ad', 'ae', 'af']
>>>

I have to compare 5 words so writing a seperate for each combination would take too long

I don see why you should use for loop like that for comparing 5 words.
Give an example of the words,and how you think the comparing output should look.

And it's not working, so how should i do shuffel thing?

import random

my_string = 'abcdefghijklmnopqrstuvxyzo'

my_list = []
for i in range(len(my_string)):
    if i == 10:
        my_list.append(my_string[:i])


r =  list(''.join(my_list))
print r #now we can shuffle
random.shuffle(r)
shuffle_string = ''.join(r)
print shuffle_string         #string
#--> ebdihfjgca
print shuffle_string.split() #make list
#--> ['ebdihfjgca']

If you want to shuffle it`s need to more than 2 elements in list.
Look into spilt(),list(),to split upp upp a string or a list.

>>> a = 'abc'
>>> list(a)
['a', 'b', 'c']

>>> a = 'a b c'.split()
>>> a
['a', 'b', 'c']

>>> from random import shuffle
>>> help(shuffle)
Help on method shuffle in module random:

shuffle(self, x, random=None, int=<type 'int'>) method of random.Random instance
    x, random=random.random -> shuffle list x in place; return None.
    
    Optional arg random is a 0-argument function returning a random
    float in [0.0, 1.0); by default, the standard random.random.

>>> #This list has 3 element
>>> l = ['a', 'b', 'c']
>>> shuffle(l)
>>> l
['b', 'a', 'c']
>>> my_list
['abcdefghij']
>>> #my_list has only 1 element an can not be shuffled
>>> print shuffle(my_list)
None
>>>

Dont use list as a variable name,it`s a python keyword

>>> list
<type 'list'>
>>> a = 'abc'
>>> list(a)
['a', 'b', 'c']

Loop over the len() of my_sting,stop at 10 and use slice.

my_string = 'abcdefghijklmnopqrstuvxyzo'

for i in range(len(my_string)):
    if i == 10:
        print my_string[:i]
        #--> abcdefghij

If you want to save 10 chars in a list.

my_string = 'abcdefghijklmnopqrstuvxyzo'

my_list = []
for i in range(len(my_string)):
    if i == 10:
        my_list.append(my_string[:i])
        
print my_list
#--> ['abcdefghij']

Make it an integer with int()

>>> paid_value = '55'
>>> type(paid_value)
<type 'str'>
>>> paid_value = int(paid_value)
>>> type(paid_value)
<type 'int'>
>>> paid_value ** 5
3025

Key in a dictionary can not use list.
If you turn it around is ok,and set list as an value.

>>> codes = {}
>>> inpt = raw_input("<<<").split()
<<<my car
>>> inpt
['my', 'car']
>>> inpt2 = raw_input("?...")
?...black
>>> inpt2
'black'
>>> codes[inpt] = inpt2

Traceback (most recent call last):
  File "<pyshell#16>", line 1, in <module>
    codes[inpt] = inpt2
TypeError: unhashable type: 'list'
>>> codes[inpt2] = inpt
>>> codes
{'black': ['my', 'car']}
>>>

>>> xdate = 5
>>> print 'value of xdate is %d' % xdata
value of xdate is 5

@doffing81 i will give som advice about code design.
This can be very important as code grow,to much code in global space can be a real pain.
when you work with function code is local to that function(you have to call it)
Learn to work with function first,of course class is also an option later.
But is important to get comfortable with function.

So some code to show you what i mean.
Look how this work,and a make some documation(called dok_string)

from random import shuffle

def make_deck():
    '''This function retur a sorted deck'''
    rank = 'A23456789TJQK'
    suit = 'CDHS'
    deck = []
    for r in list(rank):
        for s in list(suit):
            card = r + s
            deck.append(card)
    return deck

def shuffle_deck(deck, number=None):
    '''Shuffle deck and return card number(5) return five card'''
    shuffle(deck)
    return [deck.pop() for k in range(number)]

def foo():
    '''Not finsih yet'''
    pass

def main():
    #Here we put it all together
    #Make a note that no code is in global space,this make it eaiser to add remove code
    #We can just add remove function.
    deck = make_deck()
    five_card = shuffle_deck(deck, 5)
    print 'A test give player five card: %s' % five_card
    #-->A test give player five card: ['AH', '5S', '9H', '2S', '9S']

if __name__ == '__main__':
    main()

One way to make a deck,that is ok to understand.
@askrabal remember that import statement shall never be inside a class or function.
Import statement shall alway be on top.

rank = 'A23456789TJQK'
suit = 'CDHS'

deck = []
for r in list(rank):
    for s in list(suit):
        card = r + s
        deck.append(card)

print deck

One with list comprehension.

deck = [rank + suit for rank in "A23456789TJQK" for suit in "CDHS"]
print deck

Shuffle deck and deal some card.

>>> from random import shuffle
>>> #Shuffle deck
>>> shuffle(deck)
>>> #Deal out 5 card
>>> [deck.pop() for k in range(5)]
['7S', 'TC', 'TD', '8C', 'QS']
