Python 如何在字典中输出列表的索引号？

我有一个字典，其中包含一个列表，其中包含多个值，我应该有一个show方法以这种格式输出字典

"
2017-02-12:
    0: Eye doctor
    1: lunch with sid
    2: dinner with Jane
2017-03-29:
    0: Change oil in blue car
    1: Fix tree near front walkway
    2: Get salad stuff
2017-05-06:
    0: Sid's birthday"

然而，用我的代码，我只能让它像这样显示

2017-02-12:
    Eye doctor
    lunch with sid
    dinner with Jane
2017-03-29:
    Change oil in blue car
    Fix tree near front walkway
    Get salad stuff
2017-05-06:
    Sid's birthday

我不知道如何在值本身之前显示索引号。我该怎么做？ 这是我当前的代码

def command_show(calendar):
    for i in calendar:
        print("    "+ i +":")
        for l in calendar[i]:
            print("        ", l)

提前谢谢

def command_show(calendar):
    for key, value in calendar.items():
    print(key + ':\n')              
    for l in calendar[key]:         
        print("    " + str(list(calendar[key].keys()).index(l)), calendar[key][l])            

说明：

打印日历日期：

 print(key + ':\n')

迭代每个日期的嵌套dict：

 for l in calendar[key]:

 list(calendar[key].keys())

列出每个日期的嵌套dict键：

 for l in calendar[key]:

 list(calendar[key].keys())

获取键的索引：

 str(list(calendar[key].keys()).index(l))

您可以尝试以下方法：

calendar={'2017-05-06': ["Sid's birthday"], '2017-03-29': ['Change oil in blue car', 'Fix tree near front walkway', 'Get salad stuff'], '2017-02-12': ['Eye doctor', 'lunch with sid', 'dinner with Jane']}

for i in calendar:
    print("    "+ i +":")
    count=0
    for l in calendar[i]:
        print("        ", str(count)+":",l)
        count+=1

输出：

2017-05-06:
     0: Sid's birthday
2017-02-12:
     0: Eye doctor
     1: lunch with sid
     2: dinner with Jane
2017-03-29:
     0: Change oil in blue car
     1: Fix tree near front walkway
     2: Get salad stuff

不要只是脱口而出代码！添加一些文本来描述此代码如何最好地回答问题，这将提高答案的长期质量，并有助于防止在审阅过程中将其删除。@NightOwl888:已添加。谢谢，谢谢，这个方法很有效！非常感谢，您是否知道如何将此输出封装到str中，我刚刚意识到它需要采用这种格式。我已经编辑了上面的实际输出格式。
