• LEVEL 2

Ch.1 - Data types:
   >>> Learn about data types.
   >>> Learn about tuples, lists and dictionaries.
   >>> Make a version of MyMagic8Ball that is much shorter to code than the one from Python Basics.

PythonNextSteps-Ch1.pdf

Ch.2 - Building GUIs:

   >>> Practise using tuples and dictionaries.

   >>> Review using tkinter and learn about some more widgets.

   >>> Build a GUI.

   >>> Build a glossary application that can easily be customised into a number of other simple cool apps too.
