How to write my permutation generation function? Help!

Question

How to write my permutation generation function with python? Help me please..

Answer 1

There is already a function `permutations()` in the 'itertools' module in Python. Why not use that?
https://docs.python.org/3/library/itertools.html#itertools.permutations

If you want to implement it yourself, you can maybe use Heap's algorithm

Answer 2

Idk what those words mean off the top of my head. But include the math in the problem and link your attempted code in the description as well.
