What is restricted-functions for?

Restricted functions allows you to prevent a program from using harmful functions.
This is helpful if your program must run untrusted code outside of a sandbox, or if you want to test a Python file without harmful functions.
Please note that this does not sandbox your code, and does not have an complete list of harmful functions. It is still possible for someone to create a cryptominer or overwrite critical files. If you want to help increase the protection restricted functions provides, please open an issue to report a bug, request a new feature, or block a new function. If you already have a solution, feel free to open a PR.
