input: Write a function to take a number from the user and print all the divisors of the number. Return the list of divisors. Use this function to print the divisors of a number and assert that the printed output contains all the expected divisors.
  assert find_divisors(10)==[1, 2, 5, 10]
  assert find_divisors(15)==[1, 3, 5, 15]
  assert find_divisors(20)==[1, 2, 4, 5, 10, 20]
  assert find_divisors(25)==[1, 5, 25]
  assert find_divisors(30)==[1, 2, 3, 5, 6, 10, 15, 30]
output: def find_divisors(n):
      divisors = []
      for i in range(1, n + 1):
          if n % i == 0:
              divisors.append(i)
      return divisors
