How to Generate Permutations of Length r in Python

Generate and print all r-length permutations of a list using Python's itertools.permutations.

permutations itertools combinations
Python 
from itertools import permutations

def show_permutations(items, r):
    result = list(permutations(items, r))
    for perm in result:
        print(perm)
    print(f"Total: {len(result)}")
