How to remove python 2.7 from MacBook Pro 14?

Hello everyone,

I have followed the instructions in this article but when I go to terminal and type python --version, it still says Python 2.7.18....How do I remove python completely from this machine?

Also when I paste these commands in the terminal I get : Permission Denied even tho I am logged in as admin

~ sudo rm -rf /Library/Frameworks/Python. framework/Versions/2.7

~ sudo rm-rf /Library/Frameworks/Python. framework/Versions/3.8

Please some help...I want to remove any python in my machine
