将字典拆分为两个列表，一个列表用于键，另一个列表用于值

Question

我想将字典拆分为两个列表。一个列表用于键，另一个列表用于值。

它应该作为原始订购

原始列表：

[{"car":45845},{"house": 123}]

预期结果：

list1 = ["car", "house"]

list2 = [45845, 123]

Answer 1

fixed_list = [x.items() for x in list]
keys,values = zip(*fixed_list)

Answer 2

list1 = [k for item in [{"car":45845},{"house": 123}] for k,v in item.iteritems()]
list2 = [v for item in [{"car":45845},{"house": 123}] for k,v in item.iteritems()]

For Python 3 use dict.items()代替dict.iteritems()

Answer 3

a =[{"car":45845},{"house": 123}]

list1 = [i.values()[0] for i in a] #iterate over values 
list2=  [i.keys()[0] for i in a]   #iterate over keys

Answer 4

original = [{"car":45845},{"house": 123}]
a_dict = {}
for o in original:
    a_dict.update(o)
print a_dict
print a_dict.keys()
print a_dict.values()

输出：

{'car': 45845, 'house': 123}
['car', 'house']
[45845, 123]
