询问UserInput，除非他们写不，否则将所有输入打印为CSV -Python

Question

我正在寻找某种方式来询问用户输入字符串，一旦完成，我想在控制台中打印所有响应。像下面一样。

while True:
    cityName = input("Write the name of the city visited and hit enter, 
    if you have another city write it after, once you are done, enter 
    no. ") 
    #Forexample user wrote, NY [hit enter], Los Angeles [hit enter], 
    #London [hit enter] No. 
    if cityName == 'no':
        break
    counter += 1 //Not sure about this part. 
    print(cityName.counter + ",") #Not sure about this part
    #I want it to print NY, Los Angeles, London. 

Answer 1

构建城市名称列表。然后打印列表项目的串联值。

city_names = []
while True:
    city_name = input(
        'Write the name of the city visited and hit enter, ' 
        'if you have another city write it after, once you '
        'are done, enter no. ') 
    if city_name == 'no': 
        break
    city_names.append(city_name)
print(', '.join(city_names))
