    NAME
         python - an interpreted, interactive,  object-oriented  pro-
         gramming language
    
    SYNOPSIS
         python [ -d ] [ -i ] [ -O ] [ -S ] [ -t ] [ -u ] [ -v ] [ -x
         ] [ -h ] [ -V ]
                [ -c command | script | - ] [ arguments ]
    
    DESCRIPTION
         Python is an interpreted, interactive, object-oriented  pro-
         gramming  language  that combines remarkable power with very
         clear syntax.  For an introduction to programming in  Python
         you are referred to the Python Tutorial.  The Python Library
         Reference documents built-in and standard types,  constants,
         functions and modules.  Finally, the Python Reference Manual
         describes the syntax and semantics of the core  language  in
         (perhaps  too) much detail.  (These documents may be located
         via the INTERNET RESOURCES below; they may be  installed  on
         your system as well.)
    
         Python's basic power can be extended with your  own  modules
         written  in  C  or C++.  On most systems such modules may be
         dynamically loaded.  Python is also adaptable as  an  exten-
         sion  language  for existing applications.  See the internal
         documentation for hints.
    
    COMMAND LINE OPTIONS
         -d   Turn on parser  debugging  output  (for  wizards  only,
              depending on compilation options).
    
         -i   When a script is passed as first  argument  or  the  -c
              option  is used, enter interactive mode after executing
              the script or  the  command.   It  does  not  read  the
              $PYTHONSTARTUP  file.   This  can  be useful to inspect
              global variables or a stack trace when a script  raises
              an exception.
    
         -O   Turn on basic optimizations.  This changes the filename
              extension  for  compiled  (bytecode) files from .pyc to
              .pyo.  Given twice, causes docstrings to be discarded.
    
         -S   Disable the import of the module  site  and  the  site-
              dependent manipulations of sys.path that it entails.
    
         -t   Issue a warning when  a  source  file  mixes  tabs  and
              spaces for indentation in a way that makes it depend on
              the worth of a tab expressed in spaces.  Issue an error
              when the option is given twice.
    
         -u   Force stdin, stdout and stderr  to  be  totally  unbuf-
              fered.
    
         -v   Print a message each  time  a  module  is  initialized,
              showing  the  place  (filename or built-in module) from
              which it is loaded.  When given twice, print a  message
              for  each file that is checked for when searching for a
              module.  Also provides information on module cleanup at
              exit.
    
         -x   Skip the first line of the source.   This  is  intended
              for  a  DOS  specific  hack  only.   Warning:  the line
              numbers in error messages will be off by one!
    
         -h   Prints the usage for  the  interpreter  executable  and
              exits.
    
         -V   Prints the Python version number of the executable  and
              exits.
    
         -c command
              Specify the command  to  execute  (see  next  section).
              This  terminates the option list (following options are
              passed as arguments to the command).
    
    INTERPRETER INTERFACE
         The interpreter interface resembles that of the UNIX  shell:
         when  called  with standard input connected to a tty device,
         it prompts for commands and executes them until  an  EOF  is
         read;  when  called with a file name argument or with a file
         as standard input, it reads and executes a script from  that
         file;  when  called  with -c command, it executes the Python
         statement(s) given as command. Here command may contain mul-
         tiple  statements separated by newlines.  Leading whitespace
         is significant in  Python  statements!   In  non-interactive
         mode, the entire input is parsed befored it is executed.
    
         If available,  the  script  name  and  additional  arguments
         thereafter  are  passed to the script in the Python variable
         sys.argv , which is a list of strings (you must first import
         sys  to  be able to access it).  If no script name is given,
         sys.argv[0] is an empty string; if -c is  used,  sys.argv[0]
         contains  the  string '-c'. Note that options interpreted by
         the Python interpreter itself are not placed in sys.argv.
    
         In interactive mode, the primary prompt is `>>>'; the second
         prompt  (which  appears  when  a command is not complete) is
         `...'.  The prompts can be changed by assignment to  sys.ps1
         or  sys.ps2. The interpreter quits when it reads an EOF at a
         prompt.  When an unhandled exception occurs, a  stack  trace
         is  printed  and  control  returns to the primary prompt; in
         non-interactive mode, the interpreter exits  after  printing
         the  stack trace.  The interrupt signal raises the Keyboard-
         Interrupt exception;  other  UNIX  signals  are  not  caught
         (except  that  SIGPIPE is sometimes ignored, in favor of the
         IOError exception).  Error messages are written to stderr.
    
    FILES AND DIRECTORIES
         These are subject to difference depending on local installa-
         tion   conventions;   ${prefix}   and   ${exec_prefix}   are
         installation-dependent and should be interpreted as for  GNU
         software;  they  may  be  the same.  The default for both is
         /usr/local.
    
         ${exec_prefix}/bin/python
              Recommended location of the interpreter.
    
         ${prefix}/lib/python<version>
         ${exec_prefix}/lib/python<version>
              Recommended locations of the directories containing the
              standard modules.
    
         ${prefix}/include/python<version>
         ${exec_prefix}/include/python<version>
              Recommended locations of the directories containing the
              include  files  needed for developing Python extensions
              and embedding the interpreter.
    
         ~/.pythonrc.py
              User-specific initialization file loaded  by  the  user
              module; not used by default or by most applications.
    
    ENVIRONMENT VARIABLES
         PYTHONHOME
              Change the location of the standard  Python  libraries.
              By    default,    the   libraries   are   searched   in
              ${prefix}/lib/python<version>                       and
              ${exec_prefix}/lib/python<version>, where ${prefix} and
              ${exec_prefix} are installation-dependent  directories,
              both defaulting to /usr/local.  When $PYTHONHOME is set
              to a single directory, its value replaces  both  ${pre-
              fix}  and  ${exec_prefix}.  To specify different values
              for these, set $PYTHONHOME to ${prefix}:${exec_prefix}.
    
         PYTHONPATH
              Augments the default search path for module files.  The
              format  is  the  same as the shell's $PATH: one or more
              directory pathnames separated by colons.   Non-existant
              directories  are  silently ignored.  The default search
              path is installation dependent,  but  generally  begins
              with   ${prefix}/lib/python<version>   (see  PYTHONHOME
              above).  The default search path is always appended  to
              $PYTHONPATH.  If a script argument is given, the direc-
              tory containing the script is inserted in the  path  in
              front  of  $PYTHONPATH.  The search path can be manipu-
              lated from within a  Python  program  as  the  variable
              sys.path .
    
         PYTHONSTARTUP
              If this is the name of a readable file, the Python com-
              mands in that file are executed before the first prompt
              is displayed in interactive mode.  The file is executed
              in  the  same name space where interactive commands are
              executed so that objects defined or imported in it  can
              be  used  without qualification in the interactive ses-
              sion.  You can also  change  the  prompts  sys.ps1  and
              sys.ps2 in this file.
    
         PYTHONDEBUG
              If this is set to a non-empty string it  is  equivalent
              to specifying the -d option.
    
         PYTHONINSPECT
              If this is set to a non-empty string it  is  equivalent
              to specifying the -i option.
    
         PYTHONUNBUFFERED
              If this is set to a non-empty string it  is  equivalent
              to specifying the -u option.
    
         PYTHONVERBOSE
              If this is set to a non-empty string it  is  equivalent
              to specifying the -v option.
