Everything in Python is an object and all variables hold references to the objects. The reference values are according to the functions; as a result, you cannot change the value of the references. However, you can change the objects if it is mutable.
In short, in Python, arguments are passed by reference for mutable objects (like lists, dictionaries) and by value for immutable objects (like integers, strings). Passing by reference means that changes to the object within a function affect the original object outside the function, while passing by value creates a copy of the object, and modifications within the function do not affect the original object.
All parameters (arguments) in the Python language are passed by reference
All parameters (arguments) in the Python language are passed by reference. It means if you change what a parameter refers to within a function, the change also reflects back in the calling function.
