Random Function Generator Based on Third-Party Libraries

This function performs different operations based on a randomly selected third-party library from the tox library. For example, if numpy is selected, it will perform matrix multiplication; if requests is selected, it will send an HTTP GET request.

Technology Stack : numpy, pandas, matplotlib, scipy, requests, flask, django, sqlalchemy, pytest, tox

Code Type : Python Function

Code Difficulty : Intermediate
