为什么我的Python字典循环后不显示结果？

Question

# 使用用户输入填充字典
responses = {}
# 设置一个标志，指出调查是否继续
polling_active = True

while polling_active:
    # 提示输入被调查者的名字和问答
    name = input("\nWhat is your name? ")
    reponse = input("Which mountain would you like to climb someday? ")

    # 将回答存储在字典中
    repeat = input("Would you like to let another person respond? (yes/no)")
    if repeat == 'no':
        polling_active = False

# 调查结束，显示结果
print("\n--- Poll Results ---")
for name, response in responses.items():
    print(f"{name} would like to climb {response}.")

倒数第二个print可以运行，但倒数第一个print没有运行，编程软件也没有报错

解决最后一个print运行的问题

Answer 1

根据你原来代码的意图，你是想创建一个空字典 responses, 然后使用name(通过input方法获得的字符串）作为这个字典中的键，并使用response（通过input方法获得的字符串）作为name键的值，在while 循环中让用户不断地输入并将结果添加到字典中
你的代码print("\n--- Poll Results ---") 在while 循环退出后一定会运行的，请确认你在控制台看到的输出。

Answer 2

你这个问题其实很简单——代码逻辑没错，但你根本没把数据存进字典里。
根本没有内容可以遍历，循环自然就“没有运行”，但也不会报错。
新手这种简单问题问ai会更高效，

responses = {}
polling_active = True

while polling_active:
    name = input("\nWhat is your name? ")
    response = input("Which mountain would you like to climb someday? ")

    # ⭐ 把数据存入字典
    responses[name] = response

    repeat = input("Would you like to let another person respond? (yes/no) ")
    if repeat == 'no':
        polling_active = False

print("\n--- Poll Results ---")

for name, response in responses.items():
    print(f"{name} would like to climb {response}.")

Answer 3

responses = {}
polling_active = True

while polling_active:
    name = input("\nWhat is your name? ")
    response = input("Which mountain would you like to climb someday? ")

    # 将回答存储到字典中（关键缺少的步骤）
    responses[name] = response

    repeat = input("Would you like to let another person respond? (yes/no) ")
    if repeat == 'no':
        polling_active = False

print("\n--- Poll Results ---")
for name, response in responses.items():
    print(f"{name} would like to climb {response}.")

Answer 4

你的代码 没有将输入存入字典 responses，后面循环读取 responses 自然什么也没有。

在输入后通过 responses[name] = reponse 写入字典即可：

# 使用用户输入填充字典
responses = {}
# 设置一个标志，指出调查是否继续
polling_active = True

while polling_active:
    # 提示输入被调查者的名字和问答
    name = input("\nWhat is your name? ")
    reponse = input("Which mountain would you like to climb someday? ")

    # 存入字典
    responses[name] = reponse

    # 将回答存储在字典中
    repeat = input("Would you like to let another person respond? (yes/no)")
    if repeat == 'no':
        polling_active = False

# 调查结束，显示结果
print("\n--- Poll Results ---")
for name, response in responses.items():
    print(f"{name} would like to climb {response}.")
