I installed Python 2.6 and Python 3.1 on Windows 7 and set environment variable: path = d:\python2.6.
When I run python in cmd, it displays the python version 2.6, which is what I want!
But, when I wrote a script in a bat file and ran it, the displayed python version was 3.1.
import sys
print (sys.version)
What's going on here?
