A Python package for generating cases in a list.
Project description
casepy
casepy is a Python package for the advanced case combination and permutation calculation.
This package is designed to be possible to calculation of the case combination and permutation from the duplicated elements.
This package is designed to calculate combinations and permutations from the duplicate elements list. You can designate the number of elements you want to select. For instance, you can get all combinations and permutations of choosing 5 elements in a given list [1,1,2,3,4,5,5].
The combination and permutation list is sorted by numerical or alphabetical. Using the n-th-permutation or n-th-combination, you can get the n-th permutation or n-th combination of a given parameter without calculating 0-th to (n-1)-th case (current method).
Installation
You can install casepy via pip from PyPI:
$ pip install casepy
Quick Start
import casepy
element_list = [1, 2, 2, 3, 4]
all_combinations = casepy.all_combinations(element_list, 2)
# [[1, 2], [1, 3], [1, 4], [2, 2], [2, 3], [2, 4], [3, 4]]
all_permutations = casepy.all_permutations(test_list, 2)
# [[1, 2], [1, 3], [1, 4], [2, 1], [2, 2], [2, 3], [2, 4], [3, 1], [3, 2], [3, 4], [4, 1], [4, 2], [4, 3]]
