Launcher arguments:
-2 : Launch the latest Python 2.x version
-3 : Launch the latest Python 3.x version
-X.Y : Launch the specified Python version
The above default to an architecture native runtime, but will select any
available. Add a "-32" to the argument to only launch 32-bit runtimes,
or add "-64" to omit 32-bit runtimes (this latter option is deprecated).
To select a specific runtime, use the -V: options.
-V:TAG : Launch a Python runtime with the specified tag
-V:COMPANY/TAG : Launch a Python runtime from the specified company and
with the specified tag
-0 --list : List the available pythons
-0p --list-paths : List with paths
If no options are given but a script is specified, the script is checked for a
shebang line. Otherwise, an active virtual environment or global default will
be selected.
See https://docs.python.org/using/windows.html#python-launcher-for-windows for
additional configuration.
The following help text is from Python:
usage: C:\Users\Radsim\AppData\Local\Programs\Python\Python312\python.exe [option] ... [-c cmd | -m mod | file | -] [arg] ...
Options (and corresponding environment variables):
-b : issue warnings about str(bytes_instance), str(bytearray_instance)
and comparing bytes/bytearray with str. (-bb: issue errors)
-B : don't write .pyc files on import; also PYTHONDONTWRITEBYTECODE=x
-c cmd : program passed in as string (terminates option list)
-d : turn on parser debugging output (for experts only, only works on
debug builds); also PYTHONDEBUG=x
-E : ignore PYTHON* environment variables (such as PYTHONPATH)
-h : print this help message and exit (also -? or --help)
-i : inspect interactively after running script; forces a prompt even
if stdin does not appear to be a terminal; also PYTHONINSPECT=x
-I : isolate Python from the user's environment (implies -E and -s)
-m mod : run library module as a script (terminates option list)
-O : remove assert and __debug__-dependent statements; add .opt-1 before
.pyc extension; also PYTHONOPTIMIZE=x
-OO : do -O changes and also discard docstrings; add .opt-2 before
.pyc extension
-P : don't prepend a potentially unsafe path to sys.path; also PYTHONSAFEPATH
-q : don't print version and copyright messages on interactive startup
-s : don't add user site directory to sys.path; also PYTHONNOUSERSITE
-S : don't imply 'import site' on initialization
-u : force the stdout and stderr streams to be unbuffered;
this option has no effect on stdin; also PYTHONUNBUFFERED=x
-v : verbose (trace import statements); also PYTHONVERBOSE=x
can be supplied multiple times to increase verbosity
-V : print the Python version number and exit (also --version)
when given twice, print more information about the build
-W arg : warning control; arg is action:message:category:module:lineno
also PYTHONWARNINGS=arg
-x : skip first line of source, allowing use of non-Unix forms of #!cmd
-X opt : set implementation-specific option
--check-hash-based-pycs always|default|never:
control how Python invalidates hash-based .pyc files
--help-env : print help about Python environment variables and exit
--help-xoptions : print help about implementation-specific -X options and exit
--help-all : print complete help information and exit
Arguments:
file : program read from script file
- : program read from stdin (default; interactive mode if a tty)
arg ...: arguments passed to program in sys.argv[1:]

1)-i
用法
py -i *.py
运行脚本之后进入交互，交互过程保留工作空间，可以获取工作空间的变量。
