1、现在有两个列表,list1 = ['key1','key2','key3']和list2 = ['1','2','3'],把他们转为这样的字典:{'key1':'1','key2':'2','key3':'3'}
1
2
3
4
5
6
7
|
>>>list1 = [ 'key1' , 'key2' , 'key3' ] >>>list2 = [ '1' , '2' , '3' ] >>> dict ( zip (list1,list2)) { 'key1' : '1' , 'key2' : '2' , 'key3' : '3' } |
2、将嵌套列表转为字典,有两种方法,
1
2
3
4
5
|
>>>new_list = [[ 'key1' , 'value1' ],[ 'key2' , 'value2' ],[ 'key3' , 'value3' ]] >>> dict ( list ) { 'key3' : 'value3' , 'key2' : 'value2' , 'key1' : 'value1' } |
或者这样:
1
2
3
4
5
6
7
8
9
10
11
12
13
|
>>>new_list = [[ 'key1' , 'value1' ],[ 'key2' , 'value2' ],[ 'key3' , 'value3' ]] >>>new_dict = {} >>> for i in new_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' } |
