I'm looking for a way to call a python script from a batch file and getting a return code from the python script. Confusing I know, but it's based on a system that's currently in use. I'd re-write it, but this way would be much, much quicker.
So:
Bat ---------------------> Python
* call python file *
Bat <--------------------------------- Python
* python does a load of work *
* and returns a return code *
The windows shell saves the return code in the ERRORLEVEL
variable:
python somescript.py
echo %ERRORLEVEL%
In the python script you can exit the script and set the return value by calling exit()
:
exit(15)
In older versions of python you might first have to import the exit()
function from the sys
module:
from sys import exit
exit(15)
