What is the output of this code? num = [1, 2, 3, 4] x = 1 for i in range(0, len(num)): x *= i print(x) by #RahulVerma

Question

Is there anyone who can help?

Answer 1

Bilge Tandogan

That is a trick question from the challenges.

The answer is 0

The reason being that x is being multiplied by a range of numbers starting from 0. len(num)==4

1 *= 0 -> 0
0 *= 1 -> 0
0 *= 2 -> 0
0 *= 3 -> 0

x = 0

Answer 2

Bilge Tandogan ,

the code as it is has an issue in the for loop:

x *= i has to be indented.

now you can try to run the code and see the result.

Answer 3

X = 0, because at the first iteration i = 0, multiple by 0 is 0

Answer 4
