input: Write a function to print a list of all the divisors of a given number. The function should take an integer as input and output the divisors as a comma-separated list. If the number is zero, the function should return an empty list since zero has no divisors.
  
  assert find_divisors(12)==[1, 2, 3, 4, 6, 12]
  assert find_divisors(0)==[]
  assert find_divisors(1)==[1]
  assert find_divisors(7)==[1, 7]
  assert find_divisors(100)==[1, 2, 4, 5, 10, 20, 25, 50, 100]
output: def find_divisors(n):
      if n == 0:
          return []
      return [i for i in range(1, n + 1) if n % i == 0]
