[已解决]二十讲课后作业

赵从文芜湖123

我的答案：
a = 0
list1 = []
length = len(str1)
for i in str1:
    if i.isupper():
        if a <= length - 7:
            if str1[a-1].islower() and str1[a+1:a+3].isupper() and str1[a+3].islower() and str1[a+4:a+7].isupper() and str1[a+7].islower():
                list1.append(str1[a+3])
    a = a + 1
print(list1)

程序结果：
['u', 'i', 'l', 'o', 'v', 'e', 'f', 'i', 's', 'h', 'c']
多了个 ‘u’
问题出在哪里？请问如何改正？

       提取前，先把 str1 处理一下，剔除每一行末尾的 '\n' 就好了。

1. str1 = 'a' + '' . join(str1 . split('\n')) + 'a'

提取前，先把 str1 处理一下，剔除每一行末尾的 '\n' 就好了。

亲爱的UU，为啥要收尾加上“a”呢？

亲爱的UU，为啥要收尾加上“a”呢？

开头加个“a”，我好像明白了，因为如果第一个是大写字母的话，会判断前一个字母是否为小写，这时候会变成[-1]，加个“a”可能就是这样想的吧？后面那个“a”没有也可以吧？

      因为这道题说，密码字符是小写字母，其两边有且仅有3个大写字母，意思是说如果有第 4 个字符存在，这个字符一定是一个小写字母，这也必须作为密码字符的判别条件。可是，第 4 个字符在字符串的首尾并不存在，这就意味着字符串的首尾和字符串内部需要设置不同的判别条件，将会使代码编写复杂化，通过在字符串首尾各添加一个小写字母之后，使整个字符串的判别条件一致起来。

      我还有另一个回帖，展示了我改写的完整代码，这个帖子目前还没有通过审核。

嗯嗯，大致明白了

嗯嗯，大致明白了

我的这句：if a <= length - 7: 可以判断尾部字符
首字符确实在我写的代码里，判断不了，任意加一个小写字母就可以了，所以
str1 = 'a' + '' . join(str1 . split('\n')) + 'a' 最后这个“a”可以不要
你看看我说的对吗？

不知道怎么发图片 笑哭
我运行的结果还是： ['u', 'i', 'l', 'o', 'v', 'e', 'f', 'i', 's', 'h', 'c']

是不是和str1的格式有关，我的字符串右边末尾没有你的\,我是用str1 = """words""" 这样的

chinajz

是的，str1='''words'''
可以：

1. str1='''words'''
   
2. str1=str1.replace("\n", "")
   
3. list1 = []
   
4. length = len(str1)
   
5. for i in str1:
   
6.     if i.isupper():
   
7.         if a <= length - 7:
   
8.             if str1[a-1].islower() and str1[a+1:a+3].isupper() and str1[a+3].islower() and str1[a+4:a+7].isupper() and str1[a+7].islower():
   
9.                 list1.append(str1[a+3])
   
10.     a = a + 1
    
11. print(list1)
