A bat file is just a file of "DOS" commands and ends in .bat

so python31.bat

will contain the single line

C:\path\ro\python\31\python.exe %*



The %* is a placeholder for any commandline arguments you give
when calling the batch file -  like sys.argv in python.

You then call it with

python31 myscript.py


There is a brief discussion and example of a bat file in the intro
to my tutor, in the What is Programming topic.
