For a language whose motto is "There should be one - and preferably only one - obvious way to do it", Python has at least four ways to handle command line arguments out-of-the-box:
* sys.argv
* argparse
* optparse
* getopt
There are, of course, additional third party modules (like opster) that also handle arguments.
- mattdeboard 13y agosys.argv is part of the interpreter. The other three are abstractions over it. optparse is deprecated (kept around for obvious backward-compat reasons) getopt is just a different API for people who feel more comfortable with C's getopt API and don't want to learn something else argparse is the CLI option parser for the future. tl;dr: There is one way to parse command line arguments: sys.argv. But there are a few abstractions of doing that available in the stdlib.
