Run python script inside bat script

Question

I'm wondering about running python script inside bat script. At first, I need to set up virtual environment which set up correctly. The last thing is to run python script. This is my bat file.

chdir C:\Projects\bob
start C:\Environments\venv\Scripts\activate
python C:\Projects\bob\main.py

Command does not starting the python script

python C:\Projects\bob\main.py

So what is your question? Doesn't it work?

The start command will run your activation script in a new terminal instance, so your venv will not be active for your next command. Use call instead:

chdir C:\Projects\bob
call C:\Environments\venv\Scripts\activate
python C:\Projects\bob\main.py

Alternatively you could forgo changing directories and calling activate all together, and just call the python executable in your venv directly

C:\Environments\venv\Scripts\python.exe C:\Projects\bob\main.py

Yes, don't bother with activating the virtual environment, in many cases it's not necessary, on the condition of course that you call explicitly the right python binary located inside the virtual environment.
