python关于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，

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

>>>dict(list)

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