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 -
io— Core tools for working with streams -
time— Time access and conversions -
argparse— Parser for command-line options, arguments and sub-commands getopt— C-style parser for command line options-
logging— Logging facility for Python -
logging.config— Logging configuration -
logging.handlers— Logging handlers getpass— Portable password input-
curses— Terminal handling for character-cell displays -
curses.textpad— Text input widget for curses programs curses.ascii— Utilities for ASCII characters-
curses.panel— A panel stack extension for curses -
platform— Access to underlying platform’s identifying data errno— Standard errno system symbols-
ctypes— A foreign function library for Python-
