input: Write a python function to find numbers between 2000 and 3000 (both included) that are divisible by 7 but not by 5.
  assert find_numbers() == '2002,2009,2016,2023,2037,...,2996'  # Replace ... with the actual sequence in between
output: def find_numbers():
      result = []
      for num in range(2000, 3001):
          if num % 7 == 0 and num % 5 != 0:
              result.append(str(num))
      return ",".join(result)
