问题
I run Linux Mint with Python 3.4.x pre-installed. I'm starting a new project and wanted to take advantage of 3.5ish stuff so I decided I would install 3.5 and create my new virtual environment pointing to it.
So, I by accident typed
sudo apt-get install python 3.5
Which I've since learned is different from
sudo apt-get install python3.5.
I know that is different because the later requires adding a new repository wherein the former I was able to do before I added the deadsnakes repo.
So, I went through the install of "python 3.5" - it asked me some questions about FTP to ined(something) or standalone, then I installed python3.5.
My question(s) is
1) What is python 3.5? (with the space), 2) Did I break anything, 3) Should I uninstall python 3.5 even though the uninstall warns me not to unless I really know what I am doing?
Thank you
回答1:
Newer versions always have newer patches and fixes. Python 3.5.2 is probably what you installed if you used sudo apt-get install python3.5. There is also Python 3.6 now.
With the space (sudo apt-get install python 3.5) it would mean install python and 3.5 so maybe it just installed/updated python2.
Anyway, having multiple versions is not an issue. You may alias each install and use them as required.
Should I uninstall python 3.5 even though the uninstall warns me not to unless I really know what I am doing?
You shall do that if no other program/dependency is lost. Have you used it in some code? (which wouldn't work if its gone!) If you haven't then go ahead uninstall it.
