python 列表轉爲字典的兩個小方法

一、如今有兩個列表,list1 = ['key1','key2','key3']和list2 = ['1','2','3'],把他們轉爲這樣的字典:{'key1':'1','key2':'2','key3':'3'}post

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

>>>list2 = ['1','2','3']ip

>>>dict(zip(list1,list2))class

{'key1':'1','key2':'2','key3':'3'}方法

二、將嵌套列表轉爲字典,有兩種方法,dict

>>>new_list= [['key1','value1'],['key2','value2'],['key3','value3']]di

>>>dict(list)字典

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

或者這樣:

>>>new_list= [['key1','value1'],['key2','value2'],['key3','value3']]

>>>new_dict = {}

>>> for i in new_list:

...   new_dict[i[0]] = i[1]                #字典賦值,左邊爲key,右邊爲value

...

>>> new_dict

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