auto_import.py

import os

'''
auto_import.py checks if modules can be imported on another python file and automatically installs modules that have not been installed.

To use auto_import.py, you must:
1. from auto_import import auto_import
2. exec(auto_import("module name"))

This way, when the user runs the program, all necessary modules will be installed on their own.
