In chapter 7 of "How to Think Like a Computer Scientist" it introduces the function "find" that will count the number of times a character or string is found in another string. You can also tell the function where in the string to start looking. I don't get the example it gives:
>>> string.find("banana", "na", 3)
4
I expected it to return 1. Starting at index 3, "na" is only found once in the remainder of the string. Even if you started at the beginning, "na" is only found twice. I don't get it.
