PCEP Control Flow and Functions 3

Question 1

What is a default parameter value in Python?

Accepted Answer

A value used when no argument is provided for that parameter

Answer

Default parameter values let you call a function without providing that argument, using the defined default instead.

Question 2

What is the output of the following?

def f(x, y=2):
    return x * y

print(f(3))

Accepted Answer

6

Answer

With only one argument provided, `y` defaults to 2, so `f(3)` computes `3 * 2 = 6`.

Question 3

Which statement about `break` in a nested loop is correct?

Accepted Answer

It exits only the innermost loop containing it

Answer

`break` only terminates the innermost loop in which it is placed; outer loops continue normally.

Question 4

What is the output of the following code?

for i in range(5):
    pass
print(i)

Accepted Answer

4

Answer

After the loop, `i` retains the last value assigned to it, which is 4 (range stops before 5).

Question 5

Which of the following is a valid way to call a function using keyword arguments?

Accepted Answer

greet(name='Alice', age=30)

Answer

Keyword arguments use `param=value` syntax within the function call parentheses.
