Python问卷调查所有用户山名输出均为最后输入值的修复问题

问题根源 #

你的代码出现该问题是因为输出阶段的变量拼写错误：

• 遍历问卷结果的for循环中，你把接收山名的变量拼写为reponse（漏写了字母s，正确拼写为response）
• 打印语句中调用的是循环外的全局变量response，这个变量最后一次存储的是最后一位用户输入的山名，因此所有输出的山名都是同一个值。

修正方法 #

只需要调整输出部分的代码，保持变量拼写一致即可，两种可选修改方式：

• 修正for循环中的变量拼写，和全局变量名保持一致

# 原错误写法：for name, reponse in responses.items():
for name, response in responses.items():
    print(name + " would like to climb " + response + ".")

• 保持for循环的变量名不变，修改打印语句调用的变量名

for name, reponse in responses.items():
    # 原错误写法：print(name + " would like to climb " + response + ".")
    print(name + " would like to climb " + reponse + ".")

完整修正后代码（保留原英文交互逻辑） #

responses = {}

# set a flag to indicate that polling is active
polling_active = True

while polling_active:
    # prompt for the person's name and response
    name = input("\nWhat is your name? ")
    response = input("Which mountain would you like to climb someday? ")
    
    # store the response in the dictionary
    responses[name] = response
    
    # find out if anyone else is going to take the poll
    repeat = input("Would you like to let another person respond? (yes/ no) ")
    if repeat == 'no':
        polling_active = False
        
# polling is complete. show the results.
print("\n--- Poll Results ---")
for name, response in responses.items():
    print(name + " would like to climb " + response + ".")
