What is sys?

sys is a built-in module in Python that provides access to system-specific parameters and functions. It allows you to interact with the Python runtime environment. Here's some key information:

• Accessing Command Line Arguments: sys.argv is a list containing the command-line arguments passed to the Python script. sys.argv[0] is the script's name.
• Modifying the Module Search Path: sys.path is a list of strings that specifies the search path for modules. You can modify this list to add directories where Python should look for modules.
• Getting the Python Version: sys.version provides the Python version string, and sys.version_info returns a tuple containing the version number components.
• Standard Input, Output, and Error Streams: sys.stdin, sys.stdout, and sys.stderr are file-like objects representing the standard input, standard output, and standard error streams, respectively.
• Exiting the Program: sys.exit() allows you to exit the Python interpreter with a specified exit code.
• Getting the Platform Name: sys.platform provides a string identifying the operating system platform.
• Maximum Recursion Depth: You can get and set the maximum depth of the Python interpreter stack with sys.getrecursionlimit() and sys.setrecursionlimit().
• Getting the Executable Path: sys.executable provides the absolute path of the Python executable binary.
• Byte Order: sys.byteorder indicates the native byte order (endianness) of the platform. It can be 'little' or 'big'.
