Recursion permutation python

WebAug 19, 2024 · In Python, the algorithm is given as: def bitStr (n, s): if n == 1: return s return [digit + bits for digit in bitStr (1, s) for bits in bitStr (n - 1, s)] print (bitStr (3, 'abc')) I'm pretty weak in algorithmic thinking and am struggling for both an intuitive understanding of this, as well as tracing it. WebThere are two ways of generating permutations in Python: Using recursion Using itertools 1. Permutations of a String using Recursion Before we learn about the predefined method in itertools library, let us first look behind the scenes.
