"Bootstrap" python script in the Windows shell without .py / .pyw associations

python, shell

Solution

You can try to create a script what is both `python` and `windows shell script`. In this case you can name you file `my_flexible_script.bat` and execute it either directly or via `python ...`.

See a content of `pylint.bat` file from pylint:

@echo off
rem = """-*-Python-*- script
rem -------------------- DOS section --------------------
rem You could set PYTHONPATH or TK environment variables here
python -x "%~f0" %*
goto exit

"""
# -------------------- Python section --------------------
import sys
from pylint import lint
lint.Run(sys.argv[1:])


DosExitLabel = """
:exit
exit(ERRORLEVEL)
rem """

It is similar to what you do, but has more compliant `dual-script` support.

Problem

Sometimes (in customer's PCs) I need a python script to execute in the Windows shell like a .CMD or .BAT, but without having the .py or .pyw extensions associated with PYTHON / PYTHONW. I came out with a pair of 'quick'n dirty' solutions: 1) ``` """ e:\devtool\python\python.exe %0 :: or %PYTHONPATH%\python.exe goto eof: """ # Python test print "[works, but shows shell errors]" ``` 2) ``` @echo off for /f "skip=4 delims=xxx" %%l in (%0) do @echo %%l | e:\devtools\python\python.exe goto :eof ::---------- # Python test print "[works better, but is somewhat messy]" ``` Do you know a better solution? (ie: more concise or elegant) Update: based on @van answer, the more concise way I found (without setting ERRORLEVEL) ``` @e:\devtools\python\python.exe -x "%~f0" %* & exit /b ### Python begins.... import sys for arg in sys.argv: print arg raw_input("It works!!!\n") ### ```
