The slice [0:2] represent positions 0 <= x < 2
Replaces the [1, 2] from [1, 2, 3, 4] with ['a', 'b']
Result: a

Read the section on sequence slicing in the Library Reference. Use the
interactive interpreter or IDLE to perform experiments, like you did,
until you understand to your satisfaction.

please explain this behavior to a newb:
>>> a = [1,2,3,4]
>>> b = ["a","b","c","d"]
>>> a
[1, 2, 3, 4]
>>> b
['a', 'b', 'c', 'd']
>>> a[0:2]
[1, 2]
>>> a
[1, 2, 3, 4]
>>> b[2:4]
['c', 'd']
>>> a[0:2] = b[0:2]
>>> b[2:4] = a[2:4]
>>> a
['a', 'b', 3, 4]

['a', 'b', 3, 4]
