41 | -E : ignore PYTHON* environment variables (such as PYTHONPATH)\n\ |
42 | -h : print this help message and exit (also -? or --help)\n\ |
43 | -i : inspect interactively after running script; forces a prompt even\n\ |
44 | if stdin does not appear to be a terminal; also PYTHONINSPECT=x\n\ |
45 | -I : isolate Python from the user's environment (implies -E and -s)\n\ |
46 | -m mod : run library module as a script (terminates option list)\n\ |
47 | -O : remove assert and __debug__-dependent statements; add .opt-1 before\n\ |
48 | .pyc extension; also PYTHONOPTIMIZE=x\n\ |
49 | -OO : do -O changes and also discard docstrings; add .opt-2 before\n\ |
50 | .pyc extension\n\ |
51 | -P : don't prepend a potentially unsafe path to sys.path\n\ |
52 | -q : don't print version and copyright messages on interactive startup\n\ |
53 | -s : don't add user site directory to sys.path; also PYTHONNOUSERSITE\n\ |

55 | -u : force the stdout and stderr streams to be unbuffered;\n\ |
56 | this option has no effect on stdin; also PYTHONUNBUFFERED=x\n\ |
57 | -v : verbose (trace import statements); also PYTHONVERBOSE=x\n\ |
58 | can be supplied multiple times to increase verbosity\n\ |
59 | -V : print the Python version number and exit (also --version)\n\ |
60 | when given twice, print more information about the build\n\ |
61 | -W arg : warning control; arg is action:message:category:module:lineno\n\ |
62 | also PYTHONWARNINGS=arg\n\ |
63 | -x : skip first line of source, allowing use of non-Unix forms of #!cmd\n\ |

77 | The following implementation-specific options are available:\n\ |
78 | \n\ |
79 | -X faulthandler: enable faulthandler\n\ |
80 | \n\ |
81 | -X showrefcount: output the total reference count and number of used\n\ |
82 | memory blocks when the program finishes or after each statement in the\n\ |
83 | interactive interpreter. This only works on debug builds\n\ |
84 | \n\ |
85 | -X tracemalloc: start tracing Python memory allocations using the\n\ |
86 | tracemalloc module. By default, only the most recent frame is stored in a\n\ |
87 | traceback of a trace. Use -X tracemalloc=NFRAME to start tracing with a\n\ |
88 | traceback limit of NFRAME frames\n\ |
89 | \n\ |
90 | -X importtime: show how long each import takes. It shows module name,\n\ |
91 | cumulative time (including nested imports) and self time (excluding\n\ |
92 | nested imports). Note that its output may be broken in multi-threaded\n\ |
93 | application. Typical usage is python3 -X importtime -c 'import asyncio'\n\ |
94 | \n\ |
95 | -X dev: enable CPython's \"development mode\", introducing additional runtime\n\ |
96 | checks which are too expensive to be enabled by default. Effect of the\n\ |
97 | developer mode:\n\ |
98 | * Add default warning filter, as -W default\n\ |
99 | * Install debug hooks on memory allocators: see the PyMem_SetupDebugHooks()\n\ |
100 | C function\n\ |
101 | * Enable the faulthandler module to dump the Python traceback on a crash\n\ |
102 | * Enable asyncio debug mode\n\ |
103 | * Set the dev_mode attribute of sys.flags to True\n\ |
104 | * io.IOBase destructor logs close() exceptions\n\ |
105 | \n\ |
106 | -X utf8: enable UTF-8 mode for operating system interfaces, overriding the default\n\ |
107 | locale-aware mode. -X utf8=0 explicitly disables UTF-8 mode (even when it would\n\ |
108 | otherwise activate automatically)\n\ |
109 | \n\ |
110 | -X pycache_prefix=PATH: enable writing .pyc files to a parallel tree rooted at the\n\ |
111 | given directory instead of to the code tree\n\ |
112 | \n\ |
113 | -X warn_default_encoding: enable opt-in EncodingWarning for 'encoding=None'\n\ |
114 | \n\ |
115 | -X no_debug_ranges: disable the inclusion of the tables mapping extra location \n\ |
116 | information (end line, start column offset and end column offset) to every \n\ |
117 | instruction in code objects. This is useful when smaller code objects and pyc \n\ |
118 | files are desired as well as suppressing the extra visual location indicators \n\ |
119 | when the interpreter displays tracebacks.\n\ |
120 | \n\ |
121 | -X frozen_modules=[on|off]: whether or not frozen modules should be used.\n\ |
122 | The default is \"on\" (or \"off\" if you are running a local build)."; |
