0基础第20讲课后题，感觉答案不对吧？
本帖最后由 fang232629 于 2021-12-28 17:32 编辑这是题目：
1. 请用已学过的知识编写程序，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Powered by bbs.fishc.com
b) 每位密码的左右两边均有且只有三个大写字母
然后这是标准答案：
str1 = '''ABSaDKSbRIHcRHGcdDIF''' #str1的字符串内容在下面，替换一下就好
countA = 0# 统计前边的大写字母
countB = 0# 统计小写字母
countC = 0# 统计后边的大写字母
length = len(str1)
for i in range(length):
if str1 == '\n':
continue
"""
|如果str1是大写字母：
|-- 如果已经出现小写字母：
|-- -- 统计后边的大写字母
|-- 如果未出现小写字母：
|-- -- 清空后边大写字母的统计
|-- -- 统计前边的大写字母
"""
if str1.isupper():
if countB:
countC += 1
else:
countC = 0
countA += 1
"""
|如果str1是小写字母：
|-- 如果小写字母前边不是三个大写字母（不符合条件）：
|-- -- 清空所有记录，重新统计
|-- 如果小写字母前边是三个大写字母（符合条件）：
|-- -- 如果已经存在小写字母：
|-- -- -- 清空所有记录，重新统计（出现两个小写字母）
|-- -- 如果该小写字母是唯一的：
|-- -- -- countB记录出现小写字母，准备开始统计countC
"""
if str1.islower():
if countA != 3:
countA = 0
countB = 0
countC = 0
else:
if countB:
countA = 0
countB = 0
countC = 0
else:
countB = 1
countC = 0
target = i
"""
|如果前边和后边都是三个大写字母：
|-- 如果后边第四个字母也是大写字母（不符合条件）：
|-- -- 清空记录B和C，重新统计
|-- 如果后边仅有三个大写字母（符合所有条件）：
|-- -- 打印结果，并清空所有记录，进入下一轮统计
"""
if countA == 3 and countC == 3:
if i+1 != length and str1.isupper():
countB = 0
countC = 0
else:
print(str1, end='')
countA = 3
countB = 0
countC = 0
然后这是我的解题：
str1 = '''ABSaDKSbRIHcRHGcdDIF''' #str1的字符串内容在下面，替换一下就好pwd = []
count = 3
for each in str1:
if each.islower():
if not (str1.islower() and str1.islower() and str1.islower() and str1.islower() and str1.islower() and str1.islower()):
pwd.append(each)
else:
continue
else:
continue
count += 1
for i in pwd:
print(i, end='')
str1是下面的内容
