列表转字典

1、现在有两个列表，list1 = ['key1','key2','key3']和list2 = ['4','5','6']，把他们转为字典：{'key1':'4','key2':'5','key3':'6'}

list1 = ['key1','key2','key3']

list2 = ['4','5','6']

dict(zip(list1,list2))

{'key1':'4','key2':'5','key3':'6'}

2、将嵌套列表转为字典的两种方法，

list1= [['key1','1'],['key2','2'],['key3','3']]

dict(list)

{'key3': '3', 'key2': '2', 'key1': '1'}


list= [['key1','value1'],['key2','value2'],['key3','value3']]

new_dict = {}

 for i in list:

...   new_dict[i[0]] = i[1]                #字典赋值，左边为key，右边为value

...

 new_dict

{'key3': 'value3', 'key2': 'value2', 'key1': 'value1'}
