The modules described in this chapter provide interfaces to operatingsystem features that are available on (almost) all operating systems,such as files and a clock. The interfaces are generally modeledafter the Unix or C interfaces, but they are available on mostother 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 ofos.stat(),os.lstat() andos.fstat(). |
| statcache | | Stat files, and remember results. |
| statvfs | | Constants for interpreting the result ofos.statvfs(). |
| filecmp | | Compare files efficiently. |
| popen2 | | Subprocesses with accessible standard I/O streams. |
| 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. |
| tempfile | | Generate temporary file names. |
| 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. |
