Data types in Python 3

Introduction In this post we will have a look at several built-in data types in Python, like numbers, strings, lists and others. I will use Ubuntu 18.04 with Python 3.5.2 for demonstration, but you can use any Python 3 interpreter, for example Python IDLE for Windows or MacOS. $ python3 Python 3.5.2 (default, Nov 12
