Pythonic Data Structures and Algorithms

Minimal and clean example implementations of data structures and algorithms in Python 3.

Contributing

Thanks for your interest in contributing! There are many ways to contribute to this project. Get started here

Tests

Use unittest

For running all tests write down:

$ python3 -m unittest discover tests

For running some specific tests you can do this as following (Ex: sort):

$ python3 -m unittest tests.test_sort

Use pytest

For running all tests write down:

$ python3 -m pytest tests

Install

If you want to use the API algorithms in your code, it is as simple as:

$ pip3 install algorithms

You can test by creating a python file: (Ex: use merge_sort in sort)

fromalgorithms.sortimportmerge_sortif__name__=="__main__":
my_list= [1, 8, 3, 5, 6]
my_list=merge_sort(my_list)
print(my_list)

Uninstall

If you want to uninstall algorithms, it is as simple as:

$ pip3 uninstall -y algorithms
