40 / 40Loops: for and whileHardPython Basics

What is the output of this nested loop structure that Ananya uses to create a multiplication pattern?

for i in range(1, 3):
    for j in range(1, 4):
        print(i * j, end=" ")
    print()

  1. 1 2 3\n2 4 6

  2. 1 2 3 4 5 6

  3. 1\n2\n3\n2\n4\n6

  4. 6 6

Show answer & explanation

Correct answer

1 2 3\n2 4 6

Explanation

The outer loop runs twice (i=1,2), and for each iteration, the inner loop multiplies i by j (1,2,3), printing: '1 2 3' then '2 4 6' on separate lines.
