I am trying to access the value of pi in Python 2.7, but it seems as if Python doesn't recognize math.pi. I am using IDLE, and when I try to print the value of math.pi, it says that "Math is not defined" or "math is not defined". I can't upgrade to the next version without risk, so is there a way to access pi in Python 2.7? Alternatively, is there another way to convert degrees to radians in Python 2.7 without dealing with Pi?

Python 2.7.5 (default, May 15 2013, 22:44:16) [MSC v.1500 64 bit (AMD64)] on win32 

Type "help", "copyright", "credits" or "license" for more information. 

>>> import math 

>>> math.pi

Check out the Python tutorial on modules and how to use them.

As for the second part of your question, Python comes with batteries included, of course:

>>> math.radians(90) 

1.5707963267948966 

>>> math.radians(180)
