One of your classmates has already posted the question.  However, you 
win the prize for a better subject line.  Or are you the same student, 
changing your name and wasting our time by starting a new thread.

Where's your main function?

Why is everything at top level, and not inside the function(s) ?

That semicolon comes from another language.  Very seldom any need for it 
in Python.

The reason the instructor told you to do 10 is probably to discourage 
you from typing separate statements for all 10.  You're undoubtedly 
supposed to use a loop.

When you asigned it, you called it value, but now you expect it to have 
another name?

Why not start by doing the first statement of the assignment, and if you 
can't make it work, or don't understand some part of the question, ask 
again?  Show your work, not just a bunch of random statements, most of 
which won't execute.

If I were wording that first question, I'd say something like:

"""
Create a function that accepts a integer as a parameter and determines 
if the number is even or odd, returning a boolean value accordingly.

Call that function multiple times from the main function, with a variety 
of values, indicating for each whether it's even or odd.
