Question

我写了那些代码，它们运行很好，并给出了正确的答案，但突然他们开始给我错误的答案或直接进入下一个代码，我不知道发生了什么？正确输入城市时，告诉我从可用选项中进行选择！和月份：月份写得正确，但仍然不是月份和日期？？？！

enter code here
print('Hello! Let\'s explore some US bikeshare data!')
# get user input for city (chicago, new york city, washington). HINT: Use a while loop to handle invalid inputs
cities = ['chicago', 'new york', 'washington']
city = input('Choose a city: \n >').lower()

if city not in cities:
    city = input('Choose from available Cities: Chicago, New York or Washington: \n >').lower()

    
if city == 'new york':
        city = 'new york city'

    
# get user input for month (all, january, february, ... , june)
months = ['all', 'January', 'Feburary', 'March', 'April', 'May', 'June']
month = input('Please select month or for all months type "all": \n >').lower()

if month not in months:
    month = 'all'
    print("This month is not available so it's gonna be all")

# get user input for day of week (all, monday, tuesday, ... sunday)
days = ['all', 'Saturday', 'Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday']
day = input('Please Choose specific day or for all days type "all": \n >')

if day not in days:
    day = 'all'
    print("That day isn't available, so it's gonna be all")

Answer 1

month = input('Please select month or for all months type "all": \n >')

删除 lower() 否则将月列表中的元素更改为小写。

Answer 2

答案是将列表中的变量设为小写现在有用了但仍然不知道它在使用大写字母之前是如何工作的，就像我发布的那样。
