I'm working with the machine_learning/frequent_pattern_growth.py

In the find_prefix_path() function (Line 243), the base_pat parameter is never used inside the function.

So, I've removed the unused function parameter base_pat from the function definition and the function calls.

The doctest failed because I've not modified the tests for the find_prefix_path() function.

Should I change both code and doctests in a single pull request?

I've updated the tests for the find_prefix_path() function to solve the build issue.
