Then when use
python my.py
from command line it use 3.6 to run.And
pip
command will install to 3.6All other version can be run with
py -version
py -3.4 my.py
will run code in 3.4.py -2.7 my.py
will run code in 2.7.py -3.4 -m pip install requests
will install Requests to 3.4This way it easy to access all version,and using
python
it will use 3.6 which should be main version on OS.
