我是靠谱客的博主阳光音响，最近开发中收集的这篇文章主要介绍TypeError: 'str' object does not support item assignment，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

 1 response = {}
 2
 3 #设置一个标志，指出调查是否进行
 4 polling_active = True
 5
 6 while polling_active:
 7
#提示输入被调查者的名字和回答
 8
name = input("nwhat is your name? ")
 9
response = input("Which moutain would you like to climb someday? ")
10
11
#将答案存储在字典中
12
response[name] = response
13
14
#看看是否还有人要参与调查
15
repeat = input('would you like to let another person respond?(yes/no)')
16
if repeat == 'no':
17
polling_active = False
18
19 #调查结束，显示结果
20 print('n--- Poll Results ---')
21 for name, response in response.items():
22
print(name + " would like to climb " + response + ".")

上述代码运行会出错：

1 what is your name? Jony
2 Which moutain would you like to climb someday? Huangshan
3 Traceback (most recent call last):
4
File "mountain_poll.py", line 12, in <module>
5
response[name] = response
6 TypeError: 'str' object does not support item assignment
7
8 ***Repl Closed***

后面进行修改（修改部分为红色加粗的代码），发现可以正常运行了，但是不知道是什么原因？希望有大神可以指导一下，谢谢大家！

repeat = input('would you like to let another person respond?(yes/no)')
16
if repeat == 'no':
17
polling_active = False
18
19 #调查结束，显示结果
20 print('n--- Poll Results ---')
21 for name, response in response.items():
22
print(name + " would like to climb " + response + ".")

修改后运行结果：

1 what is your name? Jony
2 Which moutain would you like to climb someday? Huangshan
