Indentation error报错？Python新手写甜点识别代码运行异常求解决

现存问题 #

• 缩进逻辑错误：原代码最后询问「是否蘸糖浆」的else分支，错误绑定到了if answer=='No'（判断是否为圆形炸面团的分支）上，导致第一个问题回答Yes的场景会异常触发后续无关询问，逻辑完全混乱
• 分支覆盖不全：所有用户回答No的末端分支没有兜底提示，部分原料组合场景没有对应输出逻辑，就会出现无结果打印的情况
• 输入兼容性差：仅支持严格匹配首字母大写的Yes/No，用户输入小写、带空格等格式都会直接跳出所有判断无输出

修复后可运行代码 #

print('Let me see what dessert you got!')
# 统一输入处理，去掉前后空格转小写，兼容用户不同输入格式
answer = input('Is your dessert round fried dough? ').strip().lower()
if answer == 'yes':
    answer2 = input('Is it dipped in syrup? ').strip().lower()
    if answer2 == 'yes':
        print('Your dessert is loukoumades')
    elif answer2 == 'no':
        answer3 = input('Is it dusted in sugar? ').strip().lower()
        if answer3 == 'yes':
            print('Your dessert is a donut')
        else:
            print('No matching dessert found for your description')
elif answer == 'no':
    answer4 = input('Is your dessert thin fried dough? ').strip().lower()
    if answer4 == 'yes':
        answer3 = input('Is it dusted in sugar? ').strip().lower()
        if answer3 == 'yes':
            print('Your dessert is churros')
        else:
            print('No matching dessert found for your description')
    elif answer4 == 'no':
        answer5 = input('Is it dipped in syrup? ').strip().lower()
        if answer5 == 'yes':
            print('Your dessert is a jalebi')
        else:
            print('No matching dessert found for your description')
else:
    print('Please enter only Yes/No as your answer')
