6. Generic Operating System Services

The modules described in this chapter provide interfaces to operating system features that are available on (almost) all operating systems, such as files and a clock. The interfaces are generally modeled after the Unix or C interfaces, but they are available on most other systems as well. Here's an overview:

`os`		Miscellaneous operating system interfaces.
`os.path`		Common pathname manipulations.
`dircache`		Return directory listing, with cache mechanism.
`stat`		Utilities for interpreting the results of `os.stat()`, `os.lstat()` and `os.fstat()`.
`statcache`		Stat files, and remember results.
`statvfs`		Constants for interpreting the result of `os.statvfs()`.
`filecmp`		Compare files efficiently.
`subprocess`		Subprocess management.
`popen2`		Subprocesses with accessible standard I/O streams.
`datetime`		Basic date and time types.
`time`		Time access and conversions.
`sched`		General purpose event scheduler.
`mutex`		Lock and queue for mutual exclusion.
`getpass`		Portable reading of passwords and retrieval of the userid.
`curses`		An interface to the curses library, providing portable terminal handling.
`curses.textpad`		Emacs-like input editing in a curses window.
`curses.wrapper`		Terminal configuration wrapper for curses programs.
`curses.ascii`		Constants and set-membership functions for ASCII characters.
`curses.panel`		A panel stack extension that adds depth to curses windows.
`getopt`		Portable parser for command line options; support both short and long option names.
`optparse`		More convenient, flexible, and powerful command-line parsing library.
`tempfile`		Generate temporary files and directories.
`errno`		Standard errno system symbols.
`glob`		Unix shell style pathname pattern expansion.
`fnmatch`		Unix shell style filename pattern matching.
`shutil`		High-level file operations, including copying.
`locale`		Internationalization services.
`gettext`		Multilingual internationalization services.
`logging`		Logging module for Python based on PEP 282.
`platform`		Retrieves as much platform identifying data as possible.
