About

PyFun provides a few useful functions for composing functions quickly.

Example

from pyfun import *
from operator import *

# Lets pre wrap some standard functions
mul    = Fn(mul)
add    = Fn(add)
reduce = Fn(reduce)
range  = Fn(range)

# Curry a function
add2 = add % 2

# Compose a function
add4 = add2 | add2

# Compose a function
add6 = add2 | add2 | add2

# factorial example
fac = reduce % mul | range % 1 | add % 1

# > fac(5)
# 120

# the above example is the same as:
#  def fac(x): 
#     return reduce(mul,range(1,x+1),1)
