Which version of Python are you using?

Using Python2 you would use something like this to create an array of names. Generally Python uses lists for arrays.
# create the name list
name_list = []...

Don't forget to set a and b to zero outside the loop.

You might want to use bind() rather then the command arg. Take a look at:

You pass variables as need as function arguments and/or returns.

Here is a rather simple example of a number of functions working together from:

The function main() can be simplified ...

I tend to agree with Gribouillis. As your program grows you can split out some classes in a linear fashion. Later on, as the bugs are worked out, turn them into modules

I tried the latest version of Eric (4.3.9). It assiste with PyQT syntax, but does not accept the newer connect style used with PyQT 4.5+. Somewhat irritating!

__str__() does operator overloading in a class and "hijacks" str() in any class instance operation that uses str(). So print crit1 will use it, because it uses str() to make it printable. Whereas...

I assume the question is:
Who is foolish enough to do my homework for me?

Why don't you just run the sample code I gave you with the image_file = "mars.jpg" and make sure you have the image file in the working directory or give it the full path.

You could do something simple like this ...

The nice thing about Xydric's approach is that it doesn't lose the important connectivity with the original dictionary via the keys ...

So you have a dictionary after all!

Dictionaries are indexed by key and the keys are in a hash order for fast lookups. They will always display in this order! If you want to sort by a certain...

This code snippet shows you how to sort more complicated objects like a list of lists (or tuples) by selecting an index of the item to sort by.

You can also use a somewhat older concept of sorting, the Schwartzian transform algorithm. This is made very easy with Python's list comprehension ...
# sort a more complex combination of...

Similar to Gribouillis' code, but uses lambda as a helper function ...
# sort a more complex combination of lists/tuples:
mylist = [
(1, ['a', '3.1', 'ad']),
(2, ['b', '4.0', 'bd']),
(3, ['c',...

You can use one of the built-in string functions ...
n = 2
digits = 3
ns = str(n).rjust(digits, '0')

print(ns) # 002

If
remove('an', 'banana') --> 'bana'
then this should be
remove('iss', 'Mississippi') --> 'Missippi'
So you can use ...
def remove(sub, s):
# replace first sub with empty string
return...

It can be as simple as this ...
import os
import time

# pick a file you have in the working directory
filename = "beachball.jpg"

# show file creation time
