import math error

You forgot to specify your Python version here.

Nothing to do with the math library.  It's a syntax error. And it
 occurs before the first call into the math library.

Ouch. input is unsafe, anot recommended. That's why python 3
 renamed the raw_input function to input,  eliminating the unsafe
 version.  Nevertheless,  I'll assume you understand the risks,
 and we'll go on with your problem.

The error is occurring while parsing the user's input,  which
 should not have a colon.  The smallest flaw with using input ()
 is that user error cause strange looking exceptions.
