"""2) When testing software, it can be useful to count the number of times that
a function is called. Without using any lists or dictionaries, define a
higher-order function count_calls that returns two functions:
- a counted version of the original function that counts the number of times
it has been called
- a function of zero arguments that returns the number of times that the
counted function is called

def counted_function():

nonlocal total
total = total + 1
return f1
def function_count():
nonlocal total
return total
return counted_function,function_countso the problem i am facing is that i can basically do what i am required to do but my function calls need to be as counted_add()(1,2) instead of counted_add(1,2) how do i go about solving that ? i mean i tried changing the return to counted_function(),function_count but than i call the function only once and total never increments. help appreciated
