Hi Erdal.

Since you're using *args, you can pass a variable number of arguments to the function. You can access them as if they were a list within the function itself. Here's an example to answer your question:

def calculate_total(*args):
     sum= 0
     for arg in args:
          sum += arg
     return sum

print(calculate_total(1, 2, 3, 4, 5))

#Should print 15

As Michael pointed out, one way to do this is with a "for" loop. Here's another one (but "reduce" might not have been introduced yet in the course): 

from functools import reduce

def calculate_total(*args):
    return reduce(lambda x, y: x+y, args)
