python 列表转为字典的两个小方法(小结)

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

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

>>>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'}
