  Python中的列表元組和字串之間的相互轉化需要利用,tuple(),list(),str().

樣本如下:

>>> the_string = "hello I‘am xiaoli!">>> #字串轉化為元組>>> the_tuple = tuple(the_string)>>> the_tuple(‘h‘, ‘e‘, ‘l‘, ‘l‘, ‘o‘, ‘ ‘, ‘I‘, "‘", ‘a‘, ‘m‘, ‘ ‘, ‘x‘, ‘i‘, ‘a‘, ‘o‘, ‘l‘, ‘i‘, ‘!‘)>>> #字串轉化為列表>>> the_list = list(the_string)>>> the_list[‘h‘, ‘e‘, ‘l‘, ‘l‘, ‘o‘, ‘ ‘, ‘I‘, "‘", ‘a‘, ‘m‘, ‘ ‘, ‘x‘, ‘i‘, ‘a‘, ‘o‘, ‘l‘, ‘i‘, ‘!‘]>>> #元組轉化為列表>>> the_list = list(the_tuple)>>> the_list[‘h‘, ‘e‘, ‘l‘, ‘l‘, ‘o‘, ‘ ‘, ‘I‘, "‘", ‘a‘, ‘m‘, ‘ ‘, ‘x‘, ‘i‘, ‘a‘, ‘o‘, ‘l‘, ‘i‘, ‘!‘]>>> the_tuple = tuple(the_list)>>> the_tuple(‘h‘, ‘e‘, ‘l‘, ‘l‘, ‘o‘, ‘ ‘, ‘I‘, "‘", ‘a‘, ‘m‘, ‘ ‘, ‘x‘, ‘i‘, ‘a‘, ‘o‘, ‘l‘, ‘i‘, ‘!‘)>>> #如果將元組和列錶轉化為字串需要join()>>> "".join(the_tuple)"hello I‘am xiaoli!">>> "".join(the_list)"hello I‘am xiaoli!">>> #如果不用join()函數>>> str(the_tuple)‘(\‘h\‘, \‘e\‘, \‘l\‘, \‘l\‘, \‘o\‘, \‘ \‘, \‘I\‘, "\‘", \‘a\‘, \‘m\‘, \‘ \‘, \‘x\‘, \‘i\‘, \‘a\‘, \‘o\‘, \‘l\‘, \‘i\‘, \‘!\‘)‘

總結一點:join是串連字元的重要方法。
