sys module in Python
The sys
module in Python provides access to some variables and functions that are used or maintained by the interpreter itself. It is a built-in module, which means it is always available to use without installing any external libraries.
Some of the commonly used functions and variables in the sys
module are:
sys.argv
: A list in Python, which contains the command-line arguments passed to the script. With this variable, you can access the command-line arguments in your Python program.sys.exit()
: This function is used to exit the Python interpreter. You can pass an optional exit code as an argument, which is returned to the calling process.sys.platform
: A string that contains the name of the operating system on which the Python interpreter is running. For example,'linux'
on Linux,'win32'
on Windows, etc.sys.version
: A string that contains the version number of the Python interpreter.sys.path
: A list of strings that specifies the search path for modules. When you import a module in Python, the interpreter searches for it in the directories listed insys.path
.sys.stdin
,sys.stdout
, andsys.stderr
: These are file-like objects that represent the standard input, output, and error streams, respectively.
These are just a few examples of what the sys
module can do. It is a powerful module and can be used to perform many system-level tasks in Python.
