Question

我刚刚开始编写本学期的编码，所以如果你能用简单的方法来帮我找到答案，我会很感激。基本上，我只是希望它打印每个字典的名称，然后列出它的内容。哦，只是你知道，我实际上甚至不喜欢体育运动，这只是我之前想要改进的家庭作业。这就是我所得到的，是的，我知道它并不像我想要的那样工作：

football = {
            'favorite player': 'Troy Aikman',
            'team': 'Dallas Cowboys',
            'number': '8',
            'position': 'quarterback'
           }
baseball = {
            'favorite player': 'Jackie Robinson',
            'team': 'Brooklyn Dodgers',
            'number': '42',
            'position': 'second baseman'
           }
hockey = {
          'favorite player': 'Wayne Gretzky',
          'team': 'New York Rangers',
          'number': '99',
          'position': 'center'
         }

sports = [football, baseball, hockey]
my_sports = ['Football', 'Baseball', 'Hockey']
for my_sport in my_sports:
    print(my_sport)
for sport in sports:
    for question, answer in sport.items():
        print(question.title + ": " + answer)
    print("\n")

我想要打印：

Football
Favorite player: Troy Aikman
Team: Dallas Cowboys
Number: 8
Position: quarterback

Baseball:
Favorite player: Jackie Robinson
Team: Brooklyn Dodgers
Number: 42
Position: second baseman

......等等。我如何实现我想要的结果？越简单越好，请使用Python 3，我对Python 2一无所知。

Answer 1

my_sports = {'Football': football, 'Baseball' : baseball, 'Hockey' : hockey}
for key,value in my_sports.items():
    print(key)

    for question, answer in value.items():
        print(question + ": " + answer)
    print("\n")

Answer 2

<强>更新：

我编辑我的答案，现在下面的代码有效：

my_sports = {'Football': football, 'Baseball' : baseball, 'Hockey' : hockey}

for key,value in my_sports.items():
    print(key)

    for question, answer in value.items():
        print(question + ": " + answer)
    print("\n")

结果如下：

Football
Favorite Player: Troy Aikman
Team: Dallas Cowboys
Number: 8
Position: quarterback


Baseball
Favorite Player: Jackie Robinson
Team: Brooklyn Dodgers
Number: 42
Position: second baseman


Hockey
Favorite Player: Wayne Gretzky
Team: New York Rangers
Number: 99
Position: center

Answer 3

你可以试试这个：

sports = {"football":football, "baseball":baseball, "hockey":hockey}
for a, b in sports.items():
    print(a)
    for c, d in b.items():
        print("{}: {}".format(c, d))

输出：

football
position: quarterback
favorite player: Troy Aikman
number: 8
team: Dallas Cowboys
baseball
position: second baseman
favorite player: Jackie Robinson
number: 42
team: Brooklyn Dodgers
hockey
position: center
favorite player: Wayne Gretzky
number: 99
team: New York Rangers

Answer 4

内置的zip函数似乎是从两个列表中组合和配对元素的最简单方法。以下是如何使用它：

sports = [football, baseball, hockey]
my_sports = ['Football', 'Baseball', 'Hockey']

for my_sport, sport in zip(my_sports, sports):
    print('\n'.join((
        '{}',  # name of sport
        'Favorite player: {favorite player}',
        'Team: {team}',
        'Number: {number}',
        'Position: {position}')).format(my_sport, **sport) + '\n'
    )

如何打印每个字典的名称？
