I have the following .bat script which is located on the Desktop. I have a python script which resides in a folder ("Folder") also on the Desktop. I can run the .bat script if both files are on the same directory but how I can access the python script when it's in "Folder"? I want this to run on other computers so I am trying to avoid defining usernames (eg. C:\Users\user_name\Desktop) unless there is a generic way to obtain user names and incorporate that into the .bat file.

The following is the .bat script:

@echo off

rem Root OSGEO4W home dir to the following directory
call "C:\OSGeo4W64\bin\o4w_env.bat"

echo.
cmd /k python "Script.py" 
@echo on

I tried inserting cd Folder before cmd /k python "Script.py but that only sets the directory and doesn't follow on to run the python script.

Any advice is appreciated!

    Do you need cmd at all? I think you can run python directly from the .bat file. That might not solve your main question, but it would be a more natural way to execute a Python script from a .bat file. Commented Feb 26, 2015 at 14:05

    @PadraicCunningham - Brilliant, many thanks for that! Although the question is solved, I noted this command down :) Commented Feb 26, 2015 at 14:05
  • @FMc - Thank you for your advice, I will definitely try that as I'm guessing it would work with the answer that's already provided. Commented Feb 26, 2015 at 14:07

You can just call it as python "folder/script.py".

Although it is slightly odd, because your "cd" solution should have worked as well, so there may be something else going on.

I believe cmd is starting a subshell, which might not inherit the current working directory from the parent batch script (I don't have a windows machine available to test at the moment)
@Vicky - Ah crap I asked a dumb question! Thank you very much, simple answer to an even simpler question!
@SimonFraser - Thanks for your tip, that makes sense. I will try and test this as I am still on the learning curve :)
@SimonFraser I'm sure you're right. I didn't even notice the "cmd" in there at the front as I am so used to writing python foo.py at the command line or in a batch file.
Just run "folder\script.py", i.e. specifying python should be redundant if your system is configured right . On a related note, if you have Python 3.3+ installed, then the .py extension should be associated with the new py.exe launcher. This lets you add #!python2 and #!python3 shebangs to the first line of your scripts to run using a particular version, without having to modify file type associations.

use

start python Folder/Script.py

in your bat-file.

It will open a separate command line window and executes the script in that window.

Thanks rherzog, I am aware of the start command but I want it to be executed in the same window (I perhaps should have mentioned it in the question).
