First, you don't need to import math because you didn't use any
functions from the math module.

When you get a NameError that means you haven't defined what the name
means yet.  Nowhere in your code did you write
    x = <something>
where <something> is an integer or expression of some sort.

Try again, but give x a value first.  Example:

>>> x = 5
>>> if x > 0 :
...     print "x is positive"
...
x is positive
>>>

This syntax error is probably due to incorrect indentation.  You
haven't shown us the _exact_ text of a.py, so this is just a guess.
