python 列表转为字典的两个小方法(小结)
人气:01、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'}
