Options (and corresponding environment variables):\n\
|
|
-b : issue warnings about str(bytes_instance), str(bytearray_instance)\n\

and comparing bytes/bytearray with str. (-bb: issue errors)\n\
|
|
-B : don't write .pyc files on import; also PYTHONDONTWRITEBYTECODE=x\n\
|
|
-c cmd : program passed in as string (terminates option list)\n\
|
|
-d : turn on parser debugging output (for experts only, only works on\n\
|
|
debug builds); also PYTHONDEBUG=x\n\
|
|
-E : ignore PYTHON* environment variables (such as PYTHONPATH)\n\
|
|
-h : print this help message and exit (also -? or --help)\n\
|
|
-i : inspect interactively after running script; forces a prompt even\n\
|
|
if stdin does not appear to be a terminal; also PYTHONINSPECT=x\n\
|
|
-I : isolate Python from the user's environment (implies -E and -s)\n\
|
|
-m mod : run library module as a script (terminates option list)\n\
|
|
-O : remove assert and __debug__-dependent statements; add .opt-1 before\n\
|
|
.pyc extension; also PYTHONOPTIMIZE=x\n\
|
|
-OO : do -O changes and also discard docstrings; add .opt-2 before\n\
|
|
.pyc extension\n\
|
|
-P : don't prepend a potentially unsafe path to sys.path; also PYTHONSAFEPATH\n\
|
|
-q : don't print version and copyright messages on interactive startup\n\
|
|
-s : don't add user site directory to sys.path; also PYTHONNOUSERSITE\n\
|
|
-S : don't imply 'import site' on initialization\n\
|
|
-u : force the stdout and stderr streams to be unbuffered;\n\
|
|
this option has no effect on stdin; also PYTHONUNBUFFERED=x\n\
|
|
-v : verbose (trace import statements); also PYTHONVERBOSE=x\n\
|
|
can be supplied multiple times to increase verbosity\n\
|
|
-V : print the Python version number and exit (also --version)\n\
|
|
when given twice, print more information about the build\n\
|
|
-W arg : warning control; arg is action:message:category:module:lineno\n\
|
|
also PYTHONWARNINGS=arg\n\
|
|
-x : skip first line of source, allowing use of non-Unix forms of #!cmd\n\
|
|
-X opt : set implementation-specific option\n\
|
|
--check-hash-based-pycs always|default|never:\n\

control how Python invalidates hash-based .pyc files\n\
|
|
--help-env : print help about Python environment variables and exit\n\

--help-xoptions : print help about implementation-specific -X options and exit\n\

The following implementation-specific options are available:\n\
|
|
\n\
|
|
-X faulthandler: enable faulthandler\n\
|
|
\n\
|
|
-X showrefcount: output the total reference count and number of used\n\
|
|
memory blocks when the program finishes or after each statement in the\n\
|
|
interactive interpreter. This only works on debug builds\n\
|
|
\n\
|
|
-X tracemalloc: start tracing Python memory allocations using the\n\
|
|
tracemalloc module. By default, only the most recent frame is stored in a\n\
|
|
traceback of a trace. Use -X tracemalloc=NFRAME to start tracing with a\n\
|
|
traceback limit of NFRAME frames\n\
|
|
\n\
|
|
-X importtime: show how long each import takes. It shows module name,\n\
|
|
cumulative time (including nested imports) and self time (excluding\n\
|
|
nested imports). Note that its output may be broken in multi-threaded\n\
|
|
application. Typical usage is python3 -X importtime -c 'import asyncio'\n\
|
|
\n\
|
|
-X dev: enable CPython's \"development mode\", introducing additional runtime\n\
|
|
checks which are too expensive to be enabled by default. Effect of the\n\
|
|
developer mode:\n\
|
|
* Add default warning filter, as -W default\n\
|
|
* Install debug hooks on memory allocators: see the PyMem_SetupDebugHooks()\n\
|
|
C function\n\
|
|
* Enable the faulthandler module to dump the Python traceback on a crash\n\
|
|
* Enable asyncio debug mode\n\
|
|
* Set the dev_mode attribute of sys.flags to True\n\
|
|
* io.IOBase destructor logs close() exceptions\n\
|
|
\n\
|
|
-X utf8: enable UTF-8 mode for operating system interfaces, overriding the default\n\
|
|
locale-aware mode. -X utf8=0 explicitly disables UTF-8 mode (even when it would\n\
|
|
otherwise activate automatically)\n\
|
|
\n\
|
|
-X pycache_prefix=PATH: enable writing .pyc files to a parallel tree rooted at the\n\
|
|
given directory instead of to the code tree\n\
|
|
\n\
|
|
-X warn_default_encoding: enable opt-in EncodingWarning for 'encoding=None'\n\
|
|
\n\
|
|
-X no_debug_ranges: disable the inclusion of the tables mapping extra location \n\
|
|
information (end line, start column offset and end column offset) to every \n\
|
|
instruction in code objects. This is useful when smaller code objects and pyc \n\
|
|
files are desired as well as suppressing the extra visual location indicators \n\
|
|
when the interpreter displays tracebacks.\n\
|
|
\n\
|
|
-X perf: activate support for the Linux \"perf\" profiler by activating the \"perf\"\n\
|
|
trampoline. When this option is activated, the Linux \"perf\" profiler will be \n\
|
|
able to report Python calls. This option is only available on some platforms and will \n\
|
|
do nothing if is not supported on the current system. The default value is \"off\".\n\
|
|
\n\
|
|
-X frozen_modules=[on|off]: whether or not frozen modules should be used.\n\
|
|
The default is \"on\" (or \"off\" if you are running a local build).\n\
|
|
\n\
|
|
-X int_max_str_digits=number: limit the size of int<->str conversions.\n\
|
|
This helps avoid denial of service attacks when parsing untrusted data.\n\
|
|
The default is sys.int_info.default_max_str_digits. 0 disables."
