This is just a module for 'toy problems'. I'm using different mathematical formulas/equations/etc. to practice and demonstrate various features in python.

The Wallis Equation Used to approximate pi as closely as you like. i -> ∞ | wallis -> π

• I have written a version that can take advantage of all of the cores of the machine that it is running on.
• It is also fully capable of running on pypy 2.4 (that is the version I have tested it with)
• For the standard version use wallis. For the multi core version use para_wallis.
• Wallis is able to gracefully handle a keyboard interrupt (ctrl + c), when this happens it returns it's current progress and exits.

>>> import maths
>>> i = 100000000
>>> maths.wallis(i)
(3.141592643066262, 100000000)
>>> cores = 4
>>> maths.para_wallis(i, cores)
3.141592643066262
