input: Write a Python function to calculate the difference between the sum of even and odd digits of a number.
  assert is_Diff(12345) == False
  assert is_Diff(1212112) == True
  assert is_Diff(1212) == False
output: def is_Diff(num):
      num_str = str(num)
      sum_even_digits = sum(int(digit) for digit in num_str if int(digit) % 2 == 0)
      sum_odd_digits = sum(int(digit) for digit in num_str if int(digit) % 2 != 0)
      return sum_even_digits == sum_odd_digits
