The sys module in Python provides access to some variables used or maintained by the interpreter and functions that interact with the interpreter. It allows you to access system-specific parameters and functions, such as command-line arguments, the Python runtime environment, and the interactive interpreter prompt. It is useful for tasks that require low-level access to the interpreter and operating system.
