Question

What is the output?
num = 0
while (num < 4):
-> num = num + 1
print(num)

Answer 1

The output of the Python code provided by the student is 4. This is due to the loop incrementing num by 1 until it is no longer less than 4, at which point the loop exits and the current value of num is printed.

Step-by-step explanation:

The student has presented a piece of Python code and is asking about its output. The code uses a while loop that increments the variable num as long as it is less than 4. Since the increment of num is done within the loop, the condition will eventually become false. Once num reaches 4, the loop terminates and the final value of num is printed, which is immediately after the loop and not indented, showing it is not part of the loop block.

The output of the code will be:

4

This is because the loop runs until num equals 4, at which point the condition num < 4 is no longer true and the loop exits. The last statement prints the current value of num, which is 4.
