Installing PIP packages issue

[Renym]

Hi everyone,

I am using Python 3.8 version and PyScripter and I could not install PIP openpyxl package following their website instructions. I am beginner in Python and any help is welcomed. First error I get (I have already run some Python codes without issues):

Error:
C:\Users\Renata>python --version
'python' is not recognized as an internal or external command,
operable program or batch file.

Another error:

Error:
C:\Users\Renata>pip install openpyxl
'pip' is not recognized as an internal or external command,
operable program or batch file.

I am aware that PIP is automatically installed with Python (I see in my PIP folder)

Look at this Thread.
You have forgot to mark box Add Python 3.8 to Path under installation.
You can fix yourselves bye adding to Environment Variables Path or reinstall,look at link under Fix Path if needed.
Add Python root folder and Scripts(where pip.exe is) folder to Path.
