How to install PyLint for Python 3

PyLint is a useful tool to improve code quality and to ensure that it complies with PEP-8 style guidelines. Sadly, Ubuntu only ships with the PyLint for Python 2.x. If you are using Python 3.x, then do the following:

• If you have the Python 2.x version of PyLint, then remove it:

$ sudo apt remove pylint

• Install the PIP installer for Python 3.x:

$ sudo apt install python3-pip

• Install the PyLint for Python 3.x using PIP3:

$ sudo pip3 install pylint

• If you need to use the GUI of PyLint, then install Tk for Python 3.x:

$ sudo apt install python3-tk

• You can now use the PyLint for Python 3.x:

$ pylint ./foo.py
$ pylint-gui

Tried with: PyLint 1.4.0, PIP 1.5.4, Python 3.4.0 and Ubuntu 14.04
