Don't make the mistake I did: do not delete python2 from Linux. My python environment on my Linux box was hopelessly messed up, so I thought I'll delete all python installations and start afresh. I did not realise how much Linux(Ubuntu) depends on python2. When I attempted to do an apt install, it started deleting all kinds of programs in /bin, /usr/bin and so on. The machine wouldn't boot up. It had to be restored from scratch. But it did achieve the original objective of having a properly functioning python :) If someone can explain this dependency of the package management system or the behavior I saw, I'd be very grateful.
