Python uses a mechanism called "pass by object reference" or "pass by assignment" when passing arguments to functions. This can be a source of confusion, as it behaves like a combination of both pass by value and pass by reference. In Python, everything is an object, and when you pass an argument to a function, you are actually passing a reference to the object. However, the way the reference is used depends on whether the object is mutable or immutable.
Let's explore the concept with code examples:
In Python, immutable objects, such as integers, strings, and tuples, cannot be modified in place. When you pass them to a function, a new reference to the object is created, and any modifications made within the function do not affect the original object.
Output:
Mutable objects, such as lists and dictionaries, can be modified in place. When you pass a mutable object to a function, any changes made to the object within the function affect the original object.
Output:
