I'm new to python and I've been trying to update from python 2 to 3 by doing apt-get install python3
and it installed but when I type python --version
on my terminal the version is 2.7.9. How can I uninstall python2 and make python3 the default version?

python2
and python3
are incompatible with each other, and a lot of the software only work with python2
. So, apt-get
does not overwrite python2
when you install python3
.
You should call Python3 with python3
command and use #!/usr/bin/python3
as the shebang in your scripts.
Wing IDE has a configuration dialog box where you can set the path to your preferred python interpreter, over-riding the default.
To do so, select the Custom
radio-button for Python Executable
in the Project Properties
dialog box and then either entering a path or clicking on the Browse
button.
The Project Properties
dialog is apparently accessible from the Project
menu and the toolbar.

You may have to run python3 instead of python, python2 is still installed on your system.

You can remove the "python" package using apt-get remove python. You can check which file belongs to which package using dpkg -S .. e.g dpkg -S `which python`– kedaMay 19, 2016 at 0:35

I just read doing so is not a good idea, because a lot of things on my system are using python2 for functionality. I'm trying to make python3 the default version for Wing IDE– KatzMay 19, 2016 at 0:37
