newbie here,
I just tried playing around with the dec function and
I get errors. Correct me if I am wrong. After getting
the input, the string.split will parse the string
across whitespace chars so in other words you get a

Whats the construct that allows to loop through a list and perform an action?
you also can add a test at the end. something like myfile = [print name for

I need to look up how to use the test command and I forgot the name of the

That was me using the import within the class. I only did it due to my
ignorance. I am not advanced enough to use it like that and know what I am
doing, so as suggested I just moved all of my imports to the top.

I have a class I am defining and then I call a function within that class.
Getting error that function call is not defined. Does the function have to be
created anywhere within a class or does it have to be defined before the call
within the class.

All,
If I have something like this:
import re
sample = 'myboss:isbad'
express = re.compile('(.*):(.*))
answer = re.match(express,sample)
how do I get it to tell me if it was a match or not. I have tried
answer.match . It just gives me an object pointer or something.
Thanks

New to Python and trying to do some class stuff with a simple task.
Problem:
1) get a list of file names in a directory
2) create variables with the same name of each filename pulled from the
directory.
3) Create an object for each and pass into the __init__ method the stringname
of the file nam
