python

Object-oriented programming and scripting language

Syntax:

python [option] ... [-c cmd | -m mod | file | -] [arg] ...

Runs on:

Neutrino

Options:

-c cmd

Pass the cmd string as the program to run. This option terminates the option list.

-d

Display debugging output from the parser. You can also enable this by setting PYTHONDEBUG to a nonzero value.

-E

Ignore Python's environment variables (such as PYTHONPATH).

-h

Print a help message, and then exit.

-i

Inspect interactively after running the script, and force prompts, even if stdin doesn't appear to be a terminal. You can also enable this by setting PYTHONINSPECT to a nonzero value.

-m mod

Run the specified library module as a script. This option terminates the option list.

-O

Optimize the generated byte code (a tad). You can also enable this by setting PYTHONOPTIMIZE to a nonzero value.

-OO

Remove doc-strings in addition to performing the -O optimizations.

-Q arg

Control the behavior of the division (/) operator, where arg is one of the following:

• old -- use floor division for integral arguments, and true division for floating-point or complex arguments.
• warn -- generate a warning if / (instead of //) is used for integer division.
• warnall -- generate a warning whenever / is used.
• new -- always perform true division.

The default is old.

---

This option will be removed in version 3.0 of Python, and the / operator will always perform true division. For more information, see http://www.python.org/dev/peps/pep-0238/.

---

-S

Don't imply import site on initialization.

-t

Issue warnings about inconsistent tab usage.

-tt

Issue errors about inconsistent tab usage.

-u

Use unbuffered binary for stdout and stderr. See the Python documentation for details on internal buffering related to this option. You can also enable this by setting PYTHONUNBUFFERED to a nonzero value.

-v

Be verbose (trace import statements). You can also enable this by setting PYTHONVERBOSE to a nonzero value.

-V

Print the Python version number, and then exit.

-W arg

Warning control; arg is action:message:category:module:lineno.

-x

Skip the first line of source, allowing the use of non-Unix forms of #!cmd.

file

Read the program from this script file.

-

Read the program from stdin (the default; Python uses interactive mode if run on a tty).

arg ...

Arguments to pass to the program in sys.argv[1:].

Description:

Python is a high-level, object-oriented programming language that supports powerful programming constructs, can be integrated with other languages such as C and C++, and is extendible through the addition of libraries and modules. You can use Python for programs and sophisticated scripts.

---

We don't support Python on Linux or Windows. If you need Python on these hosts, you should download it from http:www.python.org.

---

Environment variables:

PYTHONCASEOK

Ignore case in import statements (Windows).

PYTHONDEBUG

Display debugging output from the parser.

PYTHONHOME

An alternate prefix directory (or prefix:exec_prefix). The default module search path uses prefix/pythonX.X.

PYTHONINSPECT

Inspect interactively after running the script, and force prompts, even if stdin doesn't appear to be a terminal.

PYTHONOPTIMIZE

Optimize the generated byte code (a tad).

PYTHONPATH

A colon-separated list of directories prefixed to the default module search path. The result is stored in sys.path.

PYTHONSTARTUP

The file to execute on interactive startup (no default).

PYTHONUNBUFFERED

Use unbuffered binary for stdout and stderr. See the Python documentation for details on internal buffering.

PYTHONVERBOSE

Be verbose (trace import statements).
