Pip/ pip3/ python3 -m pip - this is the npm for Python. Upd: I keep seeing this upvoted notice that this is a 9-year old answer, things have changed.įrom a superuser perspective (not Python developer's), the next things I'd suggest learning to use: Go and sudo apt-get install python3 and code for 3.x Python bravely just remember to launch your scripts with python3 and use #!/usr/bin/env python3 shebang line. If you don't care about fancy gears of your system and just need newer Python - see no obstacles. This can't be done easily that is, you can't just "switch" your system to Python 2.7 and delete the older version.īut. To switch the system to Python 2.7 there needs to be done a piece of work, consisting of updating and re-testing all the scripts. At the moment, the code runs on Python 2.6 - so this version is the default upon installation and the code won't easily run on, say, Python 2.7 - because incompatibilities exist. So in fact, fairly large part of the system is written in Python. Of particular importance is the fact that one of Ubuntu policies is to extensively use Python for writing end-user software.
For instance, Python 2.6, Python 2.7, Python 3.1 all live in separate packages on Ubuntu.
Some major, very- and incompatibly-different versions get their own packages. As others already noted, bare sudo apt-get install package will install latest available version, replacing the older one if needed.īut with some software (among which is Python) the situation is somewhat different.
