You can take a look at this code. Python also have a CSV module
my_list = []
with open('my_csv.txt') as f:
l = [i.strip().split(',') for i in f]
for i in range(len(l)):
my_list.append([int(n) for n in l[i]])
print my_list
print my_list[0][1] #Take out a number
print my_list[-1] #Take out last line of numbers

If you have question dont use a 6 year old post that has been marked solved. Make a new post,just copy some code from older post if you have question about it.
what has fileHandle been replaced with in python 3.1
FileHandle is just a variable name used by vega. You can use whatever name you want. Here is the same code for python 3
# Testet work for python 3
# read a text file as a list of lines
# find the last line, change to a file you have
fileHandle = open ('test3.txt')
lineList = fileHandle.readlines()
fileHandle.close()
print (lineList)
print ("The last line is:")
print (lineList[len(lineList)-1])
# or simply
print (lineList[-1])
Or if we use an other name than FileHandle just f
# Testet work for python 3
# read a text file as a list of lines
# find the last line, change to a file you have
f = open ('test3.txt')
lineList = f.readlines()
f.close()
print (lineList)
print ("The last line is:")
print (lineList[len(lineList)-1])
# or simply
print (lineList[-1])
Postet over is a more modern solution by tony. with open() close the file object auto,so no need for close()
thanks. What are major differences using Iron Python vs Python 2.6.6?
With ironpython you can use the .Net(framework)library. Same as Jython there you can use java library. You write in python,and import from Net library.
IronPython is an implementation of the Python programming language running under .NET and Silverlight. It supports an interactive console with fully dynamic compilation. It's well integrated with the rest of the .NET Framework and makes all .NET libraries easily available to Python programmers, while maintaining compatibility with the Python language. There also is Visual Studio tooling integration.
I have been told by a number of people to use xpath instead of regex for some of my regex searches.
What are you searching?
Some notes about XML/webpages here is regex not the right tool. If you are parsing(searching) XML/html you should use beautifulsoup / lxml(has XPath built in) that is designed exactly for this purpose.
Dident get you pysnmp script to work. Here is a working py2exe kode.

You should(most) read some tutorials/book about using classes. The way you are doing is not god at all and wrong. Like basic thing that a class need the self keyword.
Can write an example that makes more sense.
class numbers(object):
def addition(self,a,b):
self.a = a
self.b = b
return self.a + self.b
def multiply(self,a,b):
self.a = a
self.b = b
return self.a * self.b
class main(numbers):
calc = numbers()
num1 = 5
num2 = 10
print calc.addition(num1, num2) #15
print calc.multiply(num1, num2) #50
import os
import fnmatch
for i,fn in enumerate(os.listdir("C:/Bilder")):

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.
humansize.py from the >>> prompt in the shell (interactive IDLE). How do I do that?
You dont do that because it wrong. To run a script. From cmdpython humansize.py or as posted by tony by using File->new window then F5(run) . If you want to use humansize.py in IDLE you have to import it. How to import and using a script look at this post. http://www.daniweb.com/forums/thread322120.html
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
>>> 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.

I keep getting an error message saying raw_input isn't defined?
If you are using python 3 change raw_input() to input() a.remove(p) will never work because string method dos not have a remove method.
Some tips about your code GDICommander's Dont use "file" as an variable name,it`s a reseverd keyword for python. You dont need "import string" to use split. So it could look like this,wihout \r\n
my_file = open("example.csv", "rb")
for line in my_file:
l = [i.strip() for i in line.split(',')]
print l
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
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
if __name__ == '__main__':
main()

A print statement should clear it up. Here first line get run,where user input return an integer. Then that integer is passed inn as an agument to function adder.
Then d take that value and put result in a new variable d. Then we print out result. Because of bad name to variables,this get more confusing than it should be.
x = int(raw_input('enter any number :'))
def adder(d):
d = d + 1
print d
adder(x)
If you want to move an item that's already in the list to the specified position, you would have to delete it and insert it at the new position. l.insert(newindex, l.pop(oldindex))
>>> l = [[5,5,5],[5,5,5,5,5],[]]
>>> l.insert(1, l.pop(2))

Use C:/Temp/test.txt or C:\\Temp\\test.txt and you need a file name loc.txt? \ Can be used as an Escape Characters an file will not be found.
but i m not getting output...wen i run a program it is showing error .
Then you have to post the error we are not mind reader. The code from -ordi- works fine,and with is a good thing to use because it close() file auto. If you use python 3 change the print statement.

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)

With pywinauto sending the source code html to notepad,not that i understand why you need this. Just copy and paste into notepad will be my easy answer for this. With a bigger website i guess sending to much text to notepad will break,or you have to break up source code.
It tok my 5sek to display result in notepad ctrl-c and ctrl-v. So to the question why to you need to display source code in notepad?
Just to show you one normal to take out som info from a website.
from BeautifulSoup import BeautifulSoup
import urllib
url = urllib.urlopen('http://beans.itcarlow.ie/prices.html')
soup = BeautifulSoup(url)
print soup #site conteds,this is the source code no need to display it in notepad.
tag = soup.findAll('strong')
print tag[0].text #$6.36 ##We have taken out price of bean from website
Cgi script is limited and if we compare something like jboss,to same in python it will be one of the many Webframework for python. Django is the most known. Some sites that run on django. http://www.djangosites.org/
richieking this was an 5 years old post. As Gribouillis posted python has never break anything before release of python 3. Python 3 has been planned for many years,and is of course the right descion for the evolution of this great language. But the are very clear that python 2 will for most pepole be the best choice for some years more.
If you look at tiobe over the last 10years rating there are not many languages that has an posetive evolution,python has is one of the few the languages that has an posetive curve.
But we are not in a hurry. Soo many versions for what?
It`s of course to get new features out,and fix some bugs. If you dont like it just stay with an older version.
I have every version from 2.5 to 3.2 installed on my laptop,that one way to test things out,and stability has never been an issue.
Dont make a mistake. yea... python is not ubuntu but at least the idea of stabilty for a software, system, tool etc are the same. Long live the snake!!!!!
ubuntu has nothing to do with python stabilty,python has been and are stable on all platform. And bugs are taken serious in python,look at bug report in python.
Like this for python 3,there has been big changes in urllib for python 3(urllib + urllib2 joined together) But i guess you havent used python 2,so the changes dosen`t matter for you.
or is there a way to convert a .html file into a .txt file?
The code under you get source kode(html),that is now just a string(text). You can not convert it to txt,you can save it as txt(but what is the point of that)
One example of what you can to: when you have read in source code(html) you can du stuff like parse out info you want,with good pareser like beautifulsoup and lxml. Or just use python string tools like find,slice.split... to take out info you need.
