import os
# works on windows nt (also xp and vista) or linux
os.system(['clear','cls'][os.name == 'nt'])
If [os.name == 'nt'] is True then this becomes effectively 1. So it picks item at index 1...

You need to move all those lines to the right by 4 spaces.

You may not want to add letters to the list that have zero count.

Also with Python3 you don't have to use
fahrenheit = (9.0 / 5.0) * celsius + 32
you can just use
fahrenheit = (9 / 5) * celsius + 32
since '/' is now floating point division and '//' is integer...

Did you download the code or retype it manually yourself?
There are some errors due to indentations and typos.

The return outside function error is really indentation error!

Seems to me that you also have to consider the time that re.compile() needs.

Some corrections:
num = 0
mylist = []

while num < 10:
num = num + 1
mylist.append(num)

print(mylist)

Asking questions is never stupid! :)

This will also trap number exceeding the index:
import string

def numtolet(num):
if num > 25: return
return string.ascii_uppercase[num]

print( numtolet(0) ) # A
print( numtolet(5)...

# staticmethod() and classmethod()
# make it easier to call one class method

class ClassA(object):
def test(this):
print this
test = staticmethod(test)

ClassA.test(4) # 4

One of the solutions is pretty straight forward, with easy logic:
list1 = [[1,2,3],[4,5,6],[7,8,9],[10,11,12]]
list2 = [1,2,3,4,11]

list3 = []
# q1 is each sublist in list1
for q1 in list1:
...

I like apple dumplings and fritters! Apple cider only if it's hard cider.

As performance is concerned, the file read from disk will be the slowest part by far!

Do you mean highest frequency first?

Simply add this to the end of the code:
print '-'*30

print "sorted by highest frequency first:"
# create list of (val, key) tuple pairs
freq_list2 =...

You are close:
fname = raw_input("enter a text file name: ")

fread = open(fname, "r")
# read the whole file into one string
text = fread.read()
fread.close()

# split the whole text string...

Vary bad manners to hijack this thread for such question.

Start your own thread and give more info!

You are in the wrong forum. Many of us went away from low level C to high level Python to solve such problems easily.

However, pyHook and pythoncom work only on Windows systems. Not too bad, since most computers in this world are using Windows. Tkinter is more cross-platform for the few odd folks that user other...

Similar to jice's code:
# simply ignore index zero
pos = [' '] * 11
print( pos )

POS = 1

pos[POS] = '->'
print( pos )

I think this is correct, because as my father explained to me, in those days C compilers had the inline assembly language option. This allowed access to the very low levels of the computer chips.

What are you going to do to the user after 3 tries?

At least for some time, it would be very nice if people indicated which version of Python they are using.

If this is truly your text file, I feel sorry for you!

I think you need to develop mask of your image to make this work.

Extension .pyd is used for C compiled library files for Python.

What is more efficient?

1) import math
2) from math import *
3) from math import sin, cos

If you are familiar with C++, Java would be the way to go. Python is simply too uncomplicated.

Since you are already used to C++ I would say use Java.

Looks like Sneekula wasted his time on you then.
I assume you also know all about img.getdata(), then you can put it together with img.putpixel().

niek_e is correct, successful compression depends on the source and the compression algorithm. Here is one example of large repeating text that the zip algorithm fails with, but bz2 compression...

I would say yes, unless your Operating System uses disk space as virtual memory.

One rude awakening with Python3 will be the frequent use of bytearrays instead of strings. It does this to handle international unicode better.

Also the online book "dive into python" has been mostly
rewritten for Python3 (check appendix A for 2to3 diffs):
