54. Amongst which of the following shows the types of function calls in Python?

1. Call by value
2. Call by reference
3. Both A and B
4. None of the mentioned above

Answer: C) Both A and B

Explanation:

Call by value and Call by reference are the types of function calls in Python.

• Call by value - When, we call a function with the values i.e. to pass the variables (not their references), the values of the passing arguments cannot be changed inside the function.
• Call by reference - When, we call a function with the reference/object, the values of the passing arguments can be changed inside the function.
