Superseded modules

The modules described in this chapter have been superseded by other modules for most use cases, and are retained primarily to preserve backwards compatibility.

Modules may appear in this chapter because they only cover a limited subset of a problem space, and a more generally applicable solution is available elsewhere in the standard library (for example, getopt covers the very specific task of "mimic the C !getopt API in Python", rather than the broader command line option parsing and argument parsing capabilities offered by optparse and argparse).

Alternatively, modules may appear in this chapter because they are deprecated outright, and awaiting removal in a future release, or they are soft deprecated and their use is actively discouraged in new projects. With the removal of various obsolete modules through 594, there are currently no modules in this latter category.
