My question is to do with calling python from a command prompt in windows 10 after installing a new version (3.9 to 3.10).

when i type (into a cmd prompt): py i get Python 3.10.0.

when i type (into a cmd prompt): python i get Python 3.9.6.

so two questions:

1. Why do i get two different versions when typing python compared to py ?
2. How can i ensure that they point to the same version or how can i select different versions ?

CodePudding user response：

This is because there are two versions of python on your computer. When you want to reference to a particular version of python just do: py - version

For example, if you want to reference to python 3.10 in cmd, do: py - 310 And when you want to reference to 3.9 do: py - 39

Make sure you have the correct spacing^
