This is one of those functions that makes us wonder why it even exists in the first place. But hey, Let’s begin exploring with this and see what kind of magic it can do!

First: What does PyRun_SimpleStringFlags() actually do? Well, according to the official documentation (which we all know is always accurate), “This function runs a string containing Python code in restricted mode.”

Okay, so let’s break that down. First, it takes a string as an argument this could be any old Python code you want to run. Secondly, it does something with the word ‘restricted’. What does that even mean? Well, according to the docs again (because we all trust them), “The restricted mode is used for sandboxing and restricts access to certain built-in functions.”

So basically, PyRun_SimpleStringFlags() lets you run Python code in a limited environment. But why would anyone want to do that? Well, let’s say you have some untrusted user input (like from a web form) and you don’t trust them not to mess with your system. You can use this function to execute their code in a restricted mode so they can’t do any damage.

PyRun_SimpleStringFlags() also has some flags that let you customize the environment even further. For example, you can set the ‘RESTRICTED_EXECUTION’ flag to restrict access to certain built-in functions (like os or sys). Or you can set the ‘NOFRAMES’ flag to disable frame creation and prevent recursion.

A function that lets you run Python code in a restricted environment with customizable flags. Who needs this kind of thing, anyway? Well, if you’re into sandboxing or want to protect your system from untrusted user input, then maybe this is the function for you. But let’s be real most of us will never use it and just stick to good old Python code without any fancy flags.
