input: Write a function to generate a Python script that takes any number of integer arguments and returns their sum. To implement this, define a function named `sum_ints` which uses the `*args` syntax to accept a variable number of integer arguments. Inside the function, iterate over each argument, adding its value to a running total. Finally, return the total sum. 
  
  assert sum_ints(3, 5, 7)==15
  assert sum_ints(1, 2, 3, 4, 5)==15
  assert sum_ints(0, 0, 0)==0
  assert sum_ints(-1, 1, -2, 2)==0
  assert sum_ints()==0
output: def sum_ints(*args):
      total = 0
      for num in args:
          total += num
      return total
