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`keda– keda2016-05-19 00:35:53 +00:00Commented May 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 IDEKatz– Katz2016-05-19 00:37:58 +00:00Commented May 19, 2016 at 0:37
