What is the default return value of a function that does not explicitly return anything?

• A. False
• B. None
• C. 0
• D. Null

Answer: (B)

In Python, when a function is defined but does not include an explicit return statement, it automatically returns a special value called `None`. This behavior signifies that the function does not return any useful data. The `None` object serves as a placeholder in Python, indicating the absence of a value or a return. It is important to understand that if a function returns `None`, this value can still be assigned to a variable, checked in conditions, and utilized in various contexts within a program. The other options provided—False, 0, and Null—are not the default outcomes of a function that lacks a return statement. Specifically, while `False` and `0` are valid values in Python, they are distinct from `None` and would only be returned if explicitly stated in the function. The term "Null" is not used in Python; instead, `None` is the correct terminology to denote the absence of a value.
