7 Functional Programming Examples in Python

Lets see 7 ways of doing functional programing in python
first we have the classic map, filter,
Map lets us go through a list and generate a new one, here we divide the original by 2
with filter we can remove those that are odd,
then with the itertools library we can have for example,
Accumulate with this one we accumulate the result of the given function, by default is addition
example of sum and power.
Groupby with this function we can group for example a list of tuples by the first index
with permutations we can have all the permutations of a list, pretty useful on some algorithms
this one is the Cartesian product of the given inputs, we can have more than 2,
Finally we have the reduce function that we can use to accumulate the list into a single value.
