I have a Raspberry Pi 3 Model B and I installed Raspbian on it using NOOBS. I want to use Python 3.6 only. Is it ok if I uninstall both Python 3.5 and 2.7? Will there be no system problems? If I yes, how do I uninstall them?

  • apt remove ... However as per joan's answer this probably won't work for python 2, in which case you should leave it be. – goldilocks Jan 31 '18 at 14:48

You have not told us which system you use so it is speculation as to whether you will have problems or not.

I believe Debian based systems use Python 2 for system purposes.

  • Joan is likely correct, in which case the system simply won't let you remove it. Do not try to force the issue ;) – goldilocks Jan 31 '18 at 14:46

Use the SDcard copier to copy the SDcard, remove each python package one at a time. If anything goes wrong, you have your SD card. If nothing goes wrong, clear the other SD card.

    Packages are installed with dependency chains, and the package manager (apt) will not let you remove critical software without some roadblocks. – goldilocks Jan 31 '18 at 14:47

    And therefor you know it is needed and you don't uninstall it. @goldilocks – FreezePhoenix Jan 31 '18 at 14:50

I tried uninstalling them one by one but I encountered a problem. The system won't boot correctly. I think both versions of Python is needed for Raspbian to run correctly.

Thanks everyone!!!
