| The Python standard library has many modules that make creating commandline tools quite simple. Often command line tools are made with pure Python modules, or are a mixture of calls to an operating system and Python, through the subprocess module. Some of the commonly used modules to create commandline tools are: optparse, configparser, and subprocess. | === Standard library support for parsing command lines === * [[https://docs.python.org/library/optparse.html|optparse]] and [[https://docs.python.org/library/argparse.html|argparse]] (optparse is marked as deprecated since the introduction of argparse with Python 2.7 and Python 3.2, use argparse unless you have to support older Python versions) * [[https://docs.python.org/2/library/getopt.html|getopt]] C-style command line parser The [[https://docs.python.org/howto/argparse.html|Argparse Tutorial]] is an excellent read for getting you started with creating command line tools.
