Question

Consider the following Python code snippet:

def multiply_numbers(a, b=2):
return a * b

result = multiply_numbers(3)
print(result)

What will be the output of the above code?

a)
5
b)
6
c)
3
d)
Error: missing required positional argument 'a'

Correct answer is option 'B'. Can you explain this answer?

Answer

Explanation:

Function Definition:
- The function `multiply_numbers` takes two parameters `a` and `b`, with a default value of 2 for `b`.
- The function returns the product of `a` and `b`.

Function Call:
- In the code snippet, the function `multiply_numbers` is called with only one argument `a=3`.
- Since the second argument `b` has a default value of 2, it uses this default value when only one argument is provided.
- Therefore, the function call `multiply_numbers(3)` is equivalent to `multiply_numbers(3, 2)`.
- The function computes and returns the result of `3 * 2`, which is 6.

Output:
- Finally, the code prints the result returned by the function, which is 6.
Therefore, the output of the above code will be 6.
