Hash(Object) Return the hash value of the object (if it has one ). hash values are integers. they are used to quickly compare dictionary keys during a dictionary lookup. numeric values that compare equal have the same hash value (even if they are of different types, as is the case for 1 and 1.0 ).

1. Return the hash value of the object, represented by an integer. Hash values can be used to quickly compare key values in dictionary search.

2. Equal values. Even if the types are different, the calculated hash values are the same.
