What Makes an Object Hashable in Python and How Is Its Hash Computed?

An object is hashable in Python if it is immutable and implements __eq__, allowing it to serve as a dictionary key; the hash value is normally derived from the object's address unless __hash__ is overridden, and equal objects must share identical hash values, influencing dictionary indexing and collision handling.
