After installing python on Windows 10, I got following error.
C:\>python
'python' is not recognized as an internal or external command,
operable program or batch file.
To my surprise py works fine but python does not work.
C:\>py

To make python works, we need to set up path. For Windows 10, python will be at following folder
C:\Users\USERNAME\AppData\Local\Programs\Python\Python36
OR
C:\Python\Python36
Use following command to set up path
C:\>path %path%;C:\Users\USERNAME\AppData\Local\Programs\Python\Python36
Once this is done, you can check the path variable using below command
C:\>echo %path%
Now let us try using python
C:\>python
