Description:

cythonintersectgroupercython 0.10

finds direct and nested intersections of lists
pip install cythonintersectgroupercython
Tested against Windows 10 / Python 3.11 / Anaconda
Important!
The module will be compiled when you import it for the first time. Cython and a C/C++ compiler must be installed!
Find the intersection of the input lists and numpy arrays and return a dictionary containing
the direct intersections, nested intersections, quantity of intersections, arrays with ID,
different values, mapped IDs, hashes, and check numpy array.

Parameters:
- list_: The input list of lists or numpy arrays
- debug: A flag to enable debugging (default: False)

Returns:
A dictionary containing the following keys:
- direct_intersections: A dictionary containing the direct intersections of the input lists and numpy arrays
- nested_intersections: An array containing the nested intersections of the input lists and numpy arrays
- qty_of_intersections: A dictionary containing the quantity of intersections for each input list or numpy array
- arrays_with_id: An array containing the arrays with ID
- different_values: The count of different values
- mapped_ids: A dictionary containing the mapped IDs
