python 中实现将两个列表合并为字典

001、方法1

>>> list1 = ["aaa", "bbb", "ccc"]
>>> list2 = [100, 500, 300]
>>> dict1 = dict(zip(list1, list2))
>>> dict1
{'aaa': 100, 'bbb': 500, 'ccc': 300}

002、方法2

>>> list1 = ["xxx", "zzz", "bbb"]
>>> list2 = [300, 100, 500]
>>> dict1 = dict()
>>> for i in range(len(list1)):
...     dict1[list1[i]] = list2[i]
...
>>> dict1
{'xxx': 300, 'zzz': 100, 'bbb': 500}
