In Python, arguments are passed by reference.

When you pass an argument to a method in Python, a reference to the object is passed instead of a copy of the object itself. This means that any changes made to the object within the method will affect the original object that was passed in.

However, it's important to note that not all objects are mutable in Python. Immutable objects like integers, strings, and tuples cannot be changed in-place, so any attempt to modify them within a method will actually create a new object. In this case, the original object remains unchanged outside of the method.

To summarize, Python passes arguments by reference, but the behavior can differ depending on whether the object is mutable or immutable.

def modify_list(my_list):
my_list.append(4)
print("Inside function:", my_list)

my_list = [1, 2, 3]
modify_list(my_list)
print("Outside function:", my_list)

Inside function: [1, 2, 3, 4]
Outside function: [1, 2, 3, 4]
