小白求助课后习题,字符串相关,做了一天没做出来
本帖最后由 liyidong3000 于 2021-9-1 11:03 编辑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
b) 每位密码的左右两边均有且只有三个大写字母
这是小甲鱼的答案,算法比较复杂。
str1 = '''ABSaDKSbRIHcRHGcdDIF'''
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
我自己写了一个
string='''ABSaDKSbRIHcRHGcdDIF'''
length=len(string)
list1=[]
for i in range(length):
if string == '\n':
continue
if string.islower() and string.isupper() and string.isupper() and string.isupper() == 0 and string.isupper() == 0:
list1.append(string)
print(list1)
感觉逻辑没问题,但是运行结果跟小甲鱼的答案不同。
字符编码这个简短的是没问题的。题目原始编码为

自己顶一下,大家帮忙看看是不是语句逻辑不通啊 666 不大不小甲鱼 发表于 2021-9-1 15:28
666
不要光6呀,帮我看看问题呢 你这个程序的问题出在字符串里的回车上。字符串里有大量的'\n',当'\n'前面的字符为2个大写字母时,str.isupper()会为True,就是把'\n'也算为大写字母了 好的,非常感谢我再来试试 liyidong3000 发表于 2021-9-1 15:39
