i just started using python and i use VS Code.

When i do

python --verion

i get python version 2

py --version

i get python version 3

i wanted to install networkx which turned out to only work with python version 3. I did multiple things to change python version to 3 but could not.

So i decided to uninstall python and went to control panel and uninstalled

python
python launcher

and restarted the computer.

But when i run

python --version

it still shows up python 2.7.18

and this is my where python output

can anyone please help me to understand whats going on and how can i get python 3 to my system.

In windows If you do not have correct environment variable set then this is likely to cause the problem.

On your Powershell if you type $env:path or on command prompt echo %PATH%

you shall see your environment variable path which you have set,

where-in, either you may not have path to directory of Python 3 or you have it appended after Python2.

i.e.:

if your result show up as (... could be other paths in your variable) then only you will get python.exe to be pointing to your Python3 path:

...
C:\Python38\Scripts;C:\Python38;
...
C:\Python27\Scripts;C:\Python27\;
...

You can download anaconda launcher and it has many python environments like jupyter notebooks or spyder with python 3 support
