Python块可与您一起使用缩进，并且每当您要从函数返回某些内容时，return应该与其余函数体相同。像这样去

def get_filters():
    """
    Asks user to specify a city, month, and day to analyze.

    Returns:
        (str) city - name of the city to analyze
        (str) month - name of the month to filter by, or "all" to apply no month filter
        (str) day - name of the day of week to filter by, or "all" to apply no day filter
    """
    print('Hello! Let\'s explore some US bikeshare data!')
    # TO DO: get user input for city (chicago, new york city, washington). HINT: Use a while loop to handle invalid inputs
    while True:
    city = input('Which city do you want to explore Chicago, New York or Washington? \n').lower()
    if city in CITIES:
        break

    # TO DO: get user input for month (all, january, february, ... , june)
    month = get_user_input('All right! now it\'s time to provide us a month name''or just say \'all\' to apply no month filter. \n(e.g.all,                              january, feburary, march, april, may, june) \n> ',MONTHS)

    # TO DO: get user input for day of week (all, monday, tuesday, ... sunday)
    day = get_user_input('One Last thing. Could you type one of the week day you want to analyse?''You can type \'all\' again to apply no  day                          filter. \n(e.g. all, monday, sunday) \n>',DAYS)

    print('-'*40)
    return city, month, day

我收到语法错误：返回外部函数
