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)) {'key1':'1','key2':'2','key3':'3'} 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) {'key3': 'value3', 'key2': 'value2', 'key1': 'value1'} 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 {'key3': 'value3', 'key2': 'value2', 'key1': 'value1'}
