如何将以下字典数组结构转换为只有一行refresh_token
结构的字典?
'city': 'continent'
这段代码给了我答案:
info = [
({'Amsterdam':10,'Berlin':20,'London':30},'Europe'),
({'Hongkong':10,'Beijng':20,'Manila':30},'Asia'),
({'Nairobi':10,'Cape Town':20,'Cairo':30},'Africa')
]
这是不正确的:
a = dict()
for t in info:
for i in t[0]:
a[i]=t[1]
{'Amsterdam': 'Europe',
'Beijng': 'Asia',
'Berlin': 'Europe',
'Cairo': 'Africa',
'Cape Town': 'Africa',
'Hongkong': 'Asia',
'London': 'Europe',
'Manila': 'Asia',
'Nairobi': 'Africa'}
另一个连接字典数组的尝试也失败了:
a = {i:t[1] for i in t[0] for t in info}
答案 0 :(得分:1)
试试这个(在3.5上测试):
a = {i: y for x, y in info for i in x}
