【转】Python 列表转为字典的两个小方法

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'}

list1 = ['key1','key2','key3']
list2 = ['1','2','3']
dict(zip(list1,list2))

2、将嵌套列表转为字典，有两种方法，

new_list= [['key1','value1'],['key2','value2'],['key3','value3']]
dict(list)

或者这样：

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
