NameError: name 'z' is not defined

运行7-10程序：

name_prompt = "\nWhat's your name? "
place_prompt = "If you could visit one place in the world, where would it be? "
continue_prompt = "\nWould you like to let someone else respond? (yes/no) "

responses = {}

while True:
 name = input(name_prompt)
 place = input(place_prompt)

 responses[name] = place

 repeat = input(continue_prompt)
 if repeat != 'yes':
 break

print("\n--- Results ---")
for name, place in responses.items():
 print(name.title() + " would like to visit " + place.title() + ".")

报错信息

$ python -u 7-10.py 

What's your name? z
Traceback (most recent call last):
 File "7-10.py", line 8, in <module>

NameError: name 'z' is not defined

难道是因为输入的时候类型是"z"导致的，而不是z？

把input换成raw_input就可以了。
书上是python3版本，而我本机是python2版本。
网上教程简易python程序NameError: name 'xxx' is not defined？

解决方案

• 1，把input换成raw_input。
• 2，本机更新成python3版本。
