Questions tagged [optparse]

optparse is a command-line argument parser for Python included in the standard library, deprecated since 2.7. It is also an unrelated command-line argument parser for Ruby.

The Python optparse module is deprecated since 2.7 and will not be developed further; development will continue with the argparse module. See PEP 0389 for more info.

Using optparse with Ruby is encouraged.
