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 interfacesio— Core tools for working with streamstime— Time access and conversionsargparse— Parser for command-line options, arguments and sub-commandsgetopt— C-style parser for command line optionslogging— Logging facility for Pythonlogging.config— Logging configurationlogging.handlers— Logging handlersgetpass— Portable password inputcurses— Terminal handling for character-cell displayscurses.textpad— Text input widget for curses programscurses.ascii— Utilities for ASCII characterscurses.panel— A panel stack extension for cursesplatform— Access to underlying platform’s identifying dataerrno— Standard errno system symbolsctypes— A foreign function library for Python- ctypes tutorial
