Command python: different meanings in command line and batch script

I have installed Anaconda with Python3. Then, I additionally created a virtual environment with Python2. There are no other Pythons on the computer. My problem:

If I run the command

python C:\Path\To\myScript.py arg1 arg2

in CMD, Python 3.4 is used to execute myScript.py (as expected/desired). But! If I create a .bat file that contains precisely the upper command, Python 2.7 is used. (I check the version with the command print(sys.version) in myScript.py).

How can I fix that?

Try specifying the full path to the Python3 (ie. /path/to/Python3 ) executable in your batch script. It's probably defaulting to the system python.

If you are using a virtualenv, and you probably should be, there is a separate python executable at venv/bin/python (or similar under Windows) - using this specific executable by absolute path is often the easiest way to ensure the correct python environment is being used, especially when scripts are run automatically or by a different user. This is entirely by design, virtualenv is often used this way.

You can either change the default version of python by changing the value of path variable this can be done by following this answer How to update PATH variable permanently from cmd? Windows

Or you can temporarily change the version you want to use follow this for that How to run different python versions in cmd

I hope my answer was helpful.

since you're using Anaconda, adding a line source deactivate before the python command would deactivate any virtualenv explicitly

edit: it's probably just deactivate for windows cmd prompt
