python - Strict comparison

Question

In javascript, there are strict comparison operators op1 === op2 and op1 !== op2 that will compare both type and value. Is there a pythonic way of achieving the same thing?

So far I've only been able to come up with the following messy conditionals:

isinstance(op1, type(op2)) and isinstance(op2, type(op1)) and op1 == op2

and

not isinstance(op1, type(op2)) or not isinstance(op2, type(op1)) or op1 != op2

Answer 1

Your approach would indeed check both value and type. There isn't a different operator in Python.

This having been said, in many cases that's not what you want - in Python's philosophy any object that behaves as a duck should be treated as a duck. You often don't want only dictionaries, you want "mapping-like" objects and so on - as long as the object can be used for the particular task then the code should accept it.
