STINNER Victor added the comment:

Many values have the same hash value, it's not an issue. The hash is only a 
best effort function to reduce hash collision, but hash collision is well 
handled in the dict type (as explained in other messages).

>>> hash(1) == hash(1.0) == hash(1.0+0j) == 1
True
>>> hash('') == hash(b'') == hash(0) == hash(0.0) == hash(0.0j) == 0
True
