The sys module in Python provides various functions and variables that are used to manipulate different parts of the Python runtime environment. It allows you to interact with the interpreter and perform tasks such as accessing command-line arguments, handling standard input and output, and managing the recursion limit. Below is a list of some commonly used functions and attributes in the sys module, along with their descriptions and links to detailed guides for each function.
