1# Program to check if a number is divisible by both 5 and 11
2

3num = int(input("Enter an integer: "))
4

5if num % 5 == 0 and num % 11 == 0:
6    print(num, "is divisible by both 5 and 11")
7else:
8    print(num, "is not divisible by both 5 and 11")

Output

Enter an integer: 55
55 is divisible by both 5 and 11

In this one

  • and, not or
  • 55 is the smallest positive example

What's going on

num % 5 == 0 and num % 11 == 0. 55 works. 10 is divisible by 5 and still fails.

or is the bug. 10 would pass. Read the title: both.

LCM of 5 and 11 is 55. That's why 55 is the test case in the output.
