Module 3 challenge: Loops :Crash Course on Python (Google IT Automation with Python Professional Certificate) Answers 2025

1. Even numbers 2–12

✔️ Correct code:

number = 2
while number <= 12:
print(number, end=" ")
number += 2

2. Correct the loop

✔️ Correct loop:

for number in range(2, 13, 2):
print(number)

3. factorial(n)

✔️ Answers:

  • While condition → n > 0

  • Decrement → n -= 1

4. multiplication_table

✔️ Ranges:

  • Outer → range(start, stop+1)

  • Inner → range(start, stop+1)

5. divisible(max, divisor)

✔️ Fill-ins:

  • Initialize → count = 0

  • Loop → for x in range(max):

  • Increment → count += 1

6. even_numbers(maximum)

✔️ Correct loop:

for x in range(2, maximum+1, 2):
return_string += str(x) + " "

7. Uninitialized loop variable

✔️ NameError ✔️

8. Final value of x

Loop: range(1, 10, 3) → values: 1, 4, 7
Final printed = 7, final value of x = 7 ✔️

9. Initial value of outer_loop

✔️ outer_loop starts at 2

10. Infinite loop reason

✔️ Variable x is not incremented

📌 Summary Table

Q Final Answer
1 number = 2, while number <= 12, number += 2
2 for number in range(2, 13, 2):
3 while n > 0, n -= 1
4 range(start, stop+1) for both loops
5 count = 0, for x in range(max), count += 1
6 range(2, maximum+1, 2)
7 NameError
8 7
9 2
10 x is not incremented
