       Python is an interpreted, interactive, object-oriented programming lan-
       guage  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 (per-
       haps too) much detail.  (These documents may be located via the  INTER-
       NET 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 extension language for existing applica-
       tions.  See the internal documentation for hints.

       Documentation for installed Python modules and packages can  be  viewed
       by running the pydoc program.

       -B     Don't  write  .py[co] files on import. See also PYTHONDONTWRITE-

       -b     Issue   warnings    about    str(bytes_instance),    str(bytear-
              ray_instance)  and  comparing  bytes/bytearray  with  str. (-bb:
              issue errors)

       -c command
              Specify the command to execute (see next section).  This  termi-
              nates the option list (following options are passed as arguments
              to the command).

       -d     Turn on parser debugging output (for wizards only, depending  on
              compilation options).

       -E     Ignore environment variables like PYTHONPATH and PYTHONHOME that
              modify the behavior of the interpreter.

       -h ,  -? ,  --help
              Prints the usage for the interpreter executable and exits.

       -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.

       -I     Run Python in isolated mode. This also implies  -E  and  -S.  In
              isolated  mode  sys.path contains neither the script's directory
              nor the user's site-packages directory. All PYTHON*  environment
              variables are ignored, too.  Further restrictions may be imposed
              to prevent the user from injecting malicious code.

       -m module-name
              Searches sys.path for the named module and runs the  correspond-
              ing .py file as a script.

       -O     Turn  on  basic optimizations.  This changes the filename exten-
              sion for compiled (bytecode) files from  .pyc  to  .pyo.   Given
              twice, causes docstrings to be discarded.

       -OO    Discard docstrings in addition to the -O optimizations.

       -q     Do  not print the version and copyright messages. These messages
              are also suppressed in non-interactive mode.

       -s     Don't add user site directory to sys.path.

       -S     Disable the import of the module  site  and  the  site-dependent
              manipulations  of  sys.path that it entails.  Also disable these
              manipulations if site is explicitly imported later.

       -u     Force  the  binary  I/O  layers  of  stdout  and  stderr  to  be
              unbuffered.   stdin is always buffered.  The text I/O layer will
              still be line-buffered.

       -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.

       -V ,  --version
              Prints the Python version number of the executable and exits.

       -W argument
              Warning control.  Python sometimes  prints  warning  message  to
              sys.stderr.   A  typical warning message has the following form:
              file:line: category:  message.   By  default,  each  warning  is
              printed  once for each source line where it occurs.  This option
              controls how often warnings are printed.   Multiple  -W  options
              may  be  given; when a warning matches more than one option, the
              action for the last matching option is  performed.   Invalid  -W
              options  are ignored (a warning message is printed about invalid
              options when the first warning is issued).  Warnings can also be
              controlled  from within a Python program using the warnings mod-

              The simplest form of argument is one  of  the  following  action
              strings  (or  a unique abbreviation): ignore to ignore all warn-
              ings; default to explicitly request the default behavior (print-
              ing  each  warning once per source line); all to print a warning
              each time it occurs (this may generate many messages if a  warn-
              ing  is  triggered  repeatedly for the same source line, such as
              inside a loop); module to print each warning only the first time
              it  occurs  in  each module; once to print each warning only the
              first time it occurs in the program; or error to raise an excep-
              tion instead of printing a warning message.

              The   full  form  of  argument  is  action:message:category:mod-
              ule:line.  Here, action is as explained above but  only  applies
              to messages that match the remaining fields.  Empty fields match
              all values; trailing empty fields may be omitted.   The  message
              field  matches  the  start  of the warning message printed; this
              match is case-insensitive.  The category field matches the warn-
              ing category.  This must be a class name; the match test whether
              the actual warning category of the message is a subclass of  the
              specified  warning category.  The full class name must be given.
              The module field matches the (fully-qualified) module name; this
              match  is  case-sensitive.  The line field matches the line num-
              ber, where zero matches all line numbers and is thus  equivalent
              to an omitted line number.

       -X option
              Set implementation specific option.

       -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!

       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  multi-
       ple  statements  separated by newlines.  Leading whitespace is signifi-
       cant in Python statements!  In non-interactive mode, the  entire  input
       is parsed before 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  KeyboardInterrupt
       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.

       These are subject to difference depending on local installation conven-
       tions; ${prefix}  and  ${exec_prefix}  are  installation-dependent  and
       should  be  interpreted  as for GNU software; they may be the same.  On
       Debian GNU/{Hurd,Linux} the default for both is /usr.

              Change  the  location  of  the  standard  Python  libraries.  By
              default, the libraries are searched in ${prefix}/lib/python<ver-
              sion>  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 ${prefix} and ${exec_prefix}.
              To specify different values for these, set $PYTHONHOME to ${pre-

              Augments the default search path for module files.   The  format
              is  the  same  as the shell's $PATH: one or more directory path-
              names  separated  by  colons.   Non-existent   directories   are
              silently  ignored.   The  default  search  path  is installation
              dependent, but generally begins  with  ${prefix}/lib/python<ver-
              sion> (see PYTHONHOME above).  The default search path is always
              appended to $PYTHONPATH.  If a script  argument  is  given,  the
              directory containing the script is inserted in the path in front
              of $PYTHONPATH.  The search path can be manipulated from  within
              a Python program as the variable sys.path.

              If  this  is the name of a readable file, the Python commands 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 session.  You can also change  the  prompts  sys.ps1
              and sys.ps2 in this file.

              Set  this  to  a  non-empty  string  to cause the time module to
              require dates specified as strings  to  include  4-digit  years,
              otherwise  2-digit  years are converted based on rules described
              in the time module documentation.

              If this is set to a non-empty string it is equivalent to  speci-
              fying  the  -O option. If set to an integer, it is equivalent to
              specifying -O multiple times.

              If this is set to a non-empty string it is equivalent to  speci-
              fying  the  -d option. If set to an integer, it is equivalent to
              specifying -d multiple times.

              If this is set to a non-empty string it is equivalent to  speci-
              fying the -B option (don't try to write .py[co] files).

              If  this is set to a non-empty string it is equivalent to speci-
              fying the -i option.

              If this is set before running the interpreter, it overrides  the
              encoding  used  for stdin/stdout/stderr, in the syntax encoding-
              name:errorhandler The errorhandler part is optional and has  the
              same meaning as in str.encode. For stderr, the errorhandler
               part is ignored; the handler will always be 'backslashreplace'.

              If  this is set to a non-empty string it is equivalent to speci-
              fying the -s option  (Don't  add  the  user  site  directory  to

              If  this is set to a non-empty string it is equivalent to speci-
              fying the -u option.

              If this is set to a non-empty string it is equivalent to  speci-
              fying  the  -v option. If set to an integer, it is equivalent to
              specifying -v multiple times.

              If this is set to a comma-separated string it is  equivalent  to
              specifying the -W option for each separate value.

              If  this  variable is set to "random", a random value is used to
              seed the hashes of str, bytes and datetime objects.

              If PYTHONHASHSEED is set to an integer value, it is  used  as  a
              fixed seed for generating the hash() of the types covered by the
              hash randomization.  Its purpose is to allow repeatable hashing,
              such  as for selftests for the interpreter itself, or to allow a
              cluster of python processes to share hash values.

              The  integer  must  be   a   decimal   number   in   the   range
              [0,4294967295].   Specifying  the value 0 will disable hash ran-
