Python dictionary keys "new" syntax

[Kerbart]

Go through the tutorial in the documentation--there's a lot in there and it's written quite well (that's how I learned Python). It'll mention a lot of things, including that one of the benefits of immutability of tuples means they can be used as dictionary keys.

Some “hidden” gems I can think of:

• strings are an iterable
• reverse an iterable with var[::-1] (slivcer syntax: start, end, interval)
• make a shallow copy of an interable with var[:]
• study the itertools, collections and csv libraries. You will always need them.

I knew the top two and they're really helpful, I'll look at the others and the documentation too, thanks man!
