How to force Python.exe to stay open when launched from Windows Task Scheduler

I am running a .py file from Windows Task Scheduler. For most files, this works fine:

  • Create a new task in TS
  • In TS, on the "Actions" tab in the "Program / script:" section, specify the path to python.exe (example: C: \ Users \ User \ Python.exe)
  • In TS under "Add Arguments" add the path to the .py file in quotes (Example: "C: \ Path \ To \ Py \ pythonfiletorun.py")

When it works correctly, Python.exe appears within a second of a second, launches the program and disappears.

However, I have one .py file that doesn't work. When I try to run it from QT Console it works fine. When I use TS process it fails. And Python.exe closes down so quickly that I can't see what is wrong.

I tried to convert everything to a batch file, so "Program / script" becomes "cmd" and "Add Arguments" becomes: / k "C: \ Path \ To \ batchfile.bat", which then contains paths and instructions.

This opens a command prompt (and keeps opening it), but from here, the main command prompt opens the python.exe command prompt, which starts and closes just as quickly.

I have tried putting / k in different places to no avail.

I've also tried putting an input qualifier at the end of the .py script (Ex: input ("Press any key ...") in the hopes that the Python.exe command will stay open, but it doesn't.

Ultimately, I need the Python.exe command to stay open so I can figure out what is wrong.

Ok, so the approach below worked (thanks everyone for their input).

First, create a batch file that reads:

start C:\Users\Path\To\Python.exe C:\Users\Path\To\PyFileToRun.py

Go to your save location and double click to make sure it works. Once that works, convert it with "-i" between the Python.exe path and the .py path file as follows:

start C:\Users\Path\To\Python.exe -i C:\Users\Path\To\PyFileToRun.py


Now go to TS and insert into "Program / script":

C:\Users\Path\To\BatchFile.bat

Leave the "Arguments" field in TS blank.

Now run the TS task and it should run and leave Python.exe open so you can investigate the problems.

Thanks again
