Python：获取与字典中的键关联的所有值，其中值可以是列表或单个项
|
我正在寻找与字典中的键相关联的所有值。有时，键仅包含一个字典，有时则包含字典列表。
a = {
\'shelf\':{
\'book\':{\'title\':\'the catcher in the rye\', \'author\':\'j d salinger\'}
}
}
b = {
\'shelf\':[
{\'book\':{\'title\':\'kafka on the shore\', \'author\':\'haruki murakami\'}},
{\'book\':{\'title\':\'atomised\', \'author\':\'michel houellebecq\'}}
]
}
def print_books(d):
if(len(d[\'shelf\']) == 1):
print d[\'shelf\'][\'book\'][\'title\']
else:
for book in d[\'shelf\']:
print book[\'book\'][\'title\']
