Before the loop, initialize the counter to 0:

    counter = 0

Inside the loop, increment the counter:

    counter = counter + 1  # can be shortened to: counter += 1

Alternatively, if you have all the strings you want to count in a
list, you can just check the length of the list:

    print(len(os.listdir("/some/directory")))
