I realise that there is already an answer for the question but its for Mac OS X 10.6.4 and the python he installed was from "python.org". My python 2.7 has come built-in in my Mac so how do I remove it? Is there any way of removing it? I have installed a python3.7 from the website and it is working perfectly but 2.7 is also working. I want to remove 2.7 and make it such that when i type "python" in terminal it runs python3.7 and not 2.7.
