D. A function cannot call itself or be passed as an argument to itself.
E. passexecutes the function body and returns its result.
F. Functions can only return numeric values or strings.

Answer: B,C

Explanation:
Positional arguments are matched to parameters by their position, so they must follow the defined order, while keyword arguments are matched by name and can be provided in any order. If a function completes without an explicit return statement, Python returns None automatically.

NEW QUESTION # 45

What is the expected result of a is b in most Python implementations?

A. Error
B. True
C. None
D. False

Answer: B

Explanation:
Python caches small integers for efficiency. Since 256 is typically within the cached range, both variables reference the same object in memory, making a is b evaluate to True.
