Try not to use str, as its used in python to change data to a string. Anyways, you created the string called: str a for statement is used to go through elements. If you think of strings as a list of characters and not just one group of letters it becomes easier. thats also why correct variable names should be used: for x in str: ... # bad ^^^ # better vvv for letter in str: ... It literally just goes through every character in the array of characters you call str.

This gives the same result without loops or variables print("o ooo oooooo o o o o o o o o o o".count("o"))

Jan Markus Because count() is not a built-in function. It is a method on the str type. https://docs.python.org/3/library/stdtypes.html#str.count

Jan Markus , XXX is right. The count method also works on lists e.g. print([1, 2, 2, 3].count(2)) and tuples, but not dictionaries or generators.
