I recently decided to brush up on my algorithms and data structures by writing them in Python. Though these are not optimized, they could be helpful for reference. Here is the Github repo: https://github.com/calebmadrigal/algorithms-in-python.

A some of the algorithms included:

• Mergesort in Python
• Quicksort in Python
• Depth-first search in Python
• Breadth-first search in Python
• Binary search tree algorithms in Python
• Dijkstra's in Python
• Hashtable implementation in Python
• Heap in Python
• Combinatoric algorithms in Python
