input: Write a function to compute the sum of two given variables and store the result in a third variable. The function should print the result.
  assert compute_sum(5, 8)==13
  assert compute_sum(10, 20)==30
  assert compute_sum(0, 0)==0
  assert compute_sum(-5, 5)==0
  assert compute_sum(3.5, 4.5)==8.0
output: def compute_sum(a, b):
      result = a + b
      print(result)
