The value of P is made available to Python as the modulus attribute of sys.hash_info. A space is another common delimiter. For str_split_n, n is the desired index of each element of the split string. Dies liegt daran, dass die Teil Zeichenfolge in der-Instanz, "bcde", gefunden wird und mit einem Element in übereinstimmt, separator bevor die Teil Zeichenfolge "f" gefunden wird.
