are you sure?
$ python pi.py
How many digits? :5
3.1415
$ python pi.py
How many digits? :10
3.141592653
$ python pi.py
How many digits? :20
3.1415926535897932384

what's the point of that? the math module already contains pi with as many
decimals as you can put in a Python float:
$ python
>>> pi = 3.1415926535897932384
>>> pi
3.1415926535897931
>>> import math
>>> math.pi
3.1415926535897931
>>> pi = math.pi
True
