How do I define a global constant...

[SpreadTooThin]

How do I define a constant that I can use in my script...
For example lets say I have a file called constants.py and in there I
have PI = 3.14

in my test script I do:

from constants import *

How do I access PI later on?


Pardon my newbie questions...

Like this:

inaccurate_esti mate_of_area = PI * radius ** 2 # :-)

You may wish to have a look at the built-in math module:

from math import *
much_better_are a = pi * radius ** 2
