'''
Class FunctionPicker takes a function (func) and multiple args or kargs as parameters and returns the
attribute result.

Instantiated FunctionPicker objects apply the function passed as a parameter to args or kargs

# Example FuncPick class instances:
mult = FuncPick(multiply, 3, 4)                                # (func, *args)
fdiv = FuncPick(floor_divide, 56, 7)                           # (func, *args)
add = FuncPick(addition, 3, 6, 81, 99)                         # (func, *args)
product = FuncPick(product_all, 3, 6, 81, 99)                  # (func, *args)
product_kwvals = FuncPick(product_value, a=5, b=6, c=7, d=8)   # (func, *kwargs)

# Print func argument results:
print(mult.result)
print(fdiv.result )
print(add.result)
print(product.result)
print(product_kwvals.result)
