I found this really neat bit of .bat file magic that will let you save your python script code in a .bat file and run it in windows just like any other script. The nice thing about this is that you don’t have to create a separate “launch.bat” file with one “start python script.py” line in it.
This makes running python scripts in Windows more like it is on a Linux/Mac where you can easily add a #!/usr/bin/env python line to the script and run it directly.
Here’s the bit of tricky batch file magic that does it:
@setlocal enabledelayedexpansion && python -x "%~f0" %* & exit /b !ERRORLEVEL! #start python code here print "hello world"
The way it works is that the first line of the file does two different things.
- starts python interpreter passing the name of the file in, and the -x option will tell it to skip the first line (containing .bat file code)
- When python finishes the script exits.
This nifty trick makes it much nicer for writing admin scripts with python on Windows.
Update: fixed to properly pass command line arguments (%* argument passes through the command line arguments for the bat file to python)
