caot execute binary file python on mac local machine

version --python shows that I have version 2.7.10 installed on my mac, it's located in /System/Library/Frameworks/Python.framework/Versions/2.7 trying to execute python from terminal raised the error: caot execute binary file

I'm trying to execute it like so hopping to successfully install awscli, that is failing while its trying to uninstall python resulting in Operation not permitted (obviously) and crashing --> aws states that if an existing version of python exist there is an option to install awscli specifically with it.
