第一个for是循环用,for word in words指所有words里的变量都挑出來用一次,形象点來说就像你在农场手挑小鸡,从一号开始选择,选择到最后一个。 words是list,也就是那串字(农场里的鸡),而word是當下抓出的字(即在你手中的那只小鸡),俗点就是您抓住一个小鸡的小鸡的手,如果你不抓上手,就简单地喊我有一号...

所有的缩进(就是Word里面的缩进)必须是四个空格。 下面是源码: # Measure some strings: words = ['cat', 'window', 'defenestrate'] for w in words: print(w, len(w)) 下面是详细解释: 保存为For_01.py,运行结果如下: cat的长度是3,window的长度是7,defenestrate的长度是12 ...
words=sentence.split(" ") 1. 步骤三:倒置每个单词 现在,我们需要倒置每个单词。可以使用字符串的切片操作来实现。下面是代码实现: reversed_words=[word[::-1]forwordinwords] 1. 这里使用了列表推导式,对每个单词进行切片操作,将其倒置。 步骤四:合并倒置后的单词 ...
