[已解决]零基础学习python【20课课后题1】疑问

来生做春风

1.请用已经学过的只是编写程序，找出小甲鱼藏在下边这个长字符串中的密码，密码的埋藏点符合以下规律：
    a)每位密码为单个小写字母
    b)没为密码的左右两边均有且只有三个大写字母

# 下面是我编写的程序

str1 = '''小甲鱼提供的超长字符串''
length = len(str1)
for i in range(3, length-2):
    if str1[i].islower():
        if str1[i-1].isupper() and str1[i-2].isupper() and str1[i-3].isupper() and str1[i-4].islower():
            j = i
            while str1[j].islower():
                j += 1
            if str1[j].isupper() and str1[j+1].isupper() and str1[j+2].isupper() and str1[j+3].islower():
                if len(str1[i:j]) > 5:
                    print('密码是:', str1[i:j])
                    print('位置', i, ',', j)

#我的输出结果
（经过验证也满足题目要求，但是没找到参考答案，我觉得是'\n'引起的，想请教一下：怎么在我的程序中加入合适的语句，从而考虑到'\n'的影响呢？）
密码是: ufvbty
位置 1553 , 1559
密码是: hiwjnvje
位置 6049 , 6057

#参考答案的输出结果

加一句这个可以去除掉\n，但是你的算法有问题，你没有理解对题目，aAAAaAAAa，中间那个小写的字母才是符合条件的密码字符之一，而不是若干连续的小写字母。

str1=str1.replace('\n','')

我不说解法，就给个建议：把代码放到代码框里可好？

比如这样

哎呀，抱歉哈！请问这个怎么放呢？我直接复制过来就是纯文本了

在你编辑帖子的时候会有类似这样的图标

点这个就好

1.请用已经学过的只是编写程序，找出小甲鱼藏在下边这个长字符串中的密码，密码的埋藏点符合以下规律：
    a)每位密码为单个小写字母
    b)没为密码的左右两边均有且只有三个大写字母

# 下面是我编写的程序

str1 = '''小甲鱼提供的超长字符串'''
length = len(str1)
for i in range(3, length-2):
    if str1[i].islower():
        if str1[i-1].isupper() and str1[i-2].isupper() and str1[i-3].isupper() and str1[i-4].islower():
            j = i
            while str1[j].islower():
                j += 1
            if str1[j].isupper() and str1[j+1].isupper() and str1[j+2].isupper() and str1[j+3].islower():
                if len(str1[i:j]) > 5:
                    print('密码是:', str1[i:j])
                    print('位置', i, ',', j)

#我的输出结果
（经过验证也满足题目要求，但是没找到参考答案，我觉得是'\n'引起的，想请教一下：怎么在我的程序中加入合适的语句，从而考虑到'\n'的影响呢？）
密码是: ufvbty
位置 1553 , 1559
密码是: hiwjnvje
位置 6049 , 6057

#参考答案的输出结果

嗯嗯，好哒！朋友，同样谢谢你

加一句这个可以去除掉\n，但是你的算法有问题，你没有理解对题目，aAAAaAAAa，中间那个小写的字母才是符合条件的密码字符之一，而不是若干连续的小写字母。

str1=str1.replace('\n','')
