**Permutations**. Let’s once again start with a definition, shall we: In mathematics, **permutation** is the act of arranging the members of a set into a sequence or order, or, if the set is already ordered, rearranging (reordering) its elements.[3] There are two main ways to calculate **permutations** and it will differ whether you allow **repetition** or. The algorithm is not as fast as the fast_permutation, but it is faster than the orginal one and than the pure **python** one available in test_itertools. The main advantage of this code is that the all **permutations** are generated in logical order: all **permutations** that starts with the first element come first. This is not the case with fast_permutation. **Python** queries related to “**permutation** with **repetition python**” **permutation** with **repetition; python permutations** without **repetition**; **python python** print **permutations** given string (including duplicates). **python python permutations** given string (including duplicates) list. **permutation** formula with **repetition**; **python python** print **permutations**.
