Please comment.

[...] Conversions between bytes or buffer objects and str objects must always be explicit, using an encoding. There are two equivalent APIs: str(b, <encoding>[, <errors>]) is equivalent to b.encode(<encoding>[, <errors>]), and bytes(s, <encoding>[, <errors>]) is equivalent to s.decode(<encoding>[, <errors>]).

This looks backwards to me. IMHO it should be:

str(b, <encoding>[, <errors>]) is equivalent to b.decode(<encoding>[, <errors>]), and bytes(s, <encoding>[, <errors>]) is equivalent to s.encode(<encoding>[, <errors>]).
