使用break推出循环

```

```python
prompt = "\nPlease enter the name of a city you have visited:"
prompt += "\n(Enter 'quit' when you are finished.)"

while Ture:
city = input(prompt)

if city == 'quit':
    break
else:
    print("I'd love to go to " + city.title() + "!")

为何运行后显示

while Ture:

NameError: name 'Ture' is not defined

这是什么原因？

写错单词了，小伙！是True
