Arguments are always passed by value in Python. Terms such as pass-by-value and pass-by-reference must be defined in such a way that is consistent across different languages. The semantics of assigning and passing are exactly the same in Python as in Java, and Java is universally described as pass . At a more fundamental level, the confusion arises from a misunderstanding about Python object-centric data model and its treatment of assignment. When asked whether Python function calling model is "call-by-value" or "call-by-reference", the correct answer is: neither. Indeed, to try to shoe-horn those terms into a conversation about Python's.

If you pass immutable arguments like integers, strings or tuples to a function, the passing acts like call-by-value. The object reference is passed to the function parameters.Effbot (aka Fredrik Lundh) has described Python's variable passing style as Always. You can think about a reference value as the address of the target object. The most common strategy is the call-by-value evaluation, sometimes also called pass-by-value. In call-by-value, the argument expression is evaluated, and the result of this evaluation is bound to the corresponding variable in the function. If you pass immutable arguments like. This will return True no matter what you pass into the function, int, float, list, dict, set, custom object (or even another function).
