获取嵌套字典的所有键 [英] Get all keys of a nested dictionary

问题描述

我有以下代码，当前仅打印初始字典的值.但是，我想遍历嵌套字典的每个键，以便最初只打印名称.请在下面查看我的代码:

I have the below code which currently just prints the values of the initial dictionary. However I would like to iterate through every key of the nested dictionary to initially just print the names. Please see my code below:

Liverpool = {
    'Keepers':{'Loris Karius':1,'Simon Mignolet':2,'Alex Manninger':3},
    'Defenders':{'Nathaniel Clyne':3,'Dejan Lovren':4,'Joel Matip':5,'Alberto Moreno':6,'Ragnar Klavan':7,'Joe Gomez':8,'Mamadou Sakho':9}
}

for k,v in Liverpool.items():
    if k =='Defenders':
       print(v)

推荐答案

以下是可打印所有团队成员的代码:

Here is code that would print all team members:

for k, v in Liverpool.items():
    for k1, v1 in v.items():
        print(k1)

因此，您只需一个一个地迭代每个内部字典并打印值即可.

So you just iterate every inner dictionary one by one and print values.
