[Microbit-Python] Sky.py Plz make it bettter

[Jim Mussared]

hi Sven,

Two main things would help you for this program:

1 - Naming the variables based on what they actually are - instead of
'H', call it 'stars'.

2 - Lists get a bit difficult when you have to remember what each of
the individual elements are for. This is exactly what classes are
designed for. Also this helps you with #1 - because you can name each
of the things.

I've attached an example.

There's also something quite subtle in this program which is the way
the display.clear() changes the behaviour from just having the stars
fade in or out, but instead every 15 frames it resets back down to a
single star showing. (Which is quite a neat effect but not what you
described -- the joys of graphics programming :D )
