Get value at list or array index or "None" if out of range in Python.md

I find list slices good for this:

>>> x = [1, 2, 3]
>>> a = x [1:2]
>>> a
[2]
>>> b = x [4:5]
>>> b
[]

So, always access x[i:i+1], if you want x[i]. You'll get a list with the required element if it exists. Otherwise, you get an empty list.
