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'}
