python 列表轉為字典的兩個小方法

1、現在有兩個列表，list1 = [‘key1’,‘key2’,‘key3’]和list2 = [‘1’,‘2’,‘3’]，把他們轉為這樣的字典：

{'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、將巢狀列表轉為字典，有兩種方法，

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

或者這樣：

>>>new_dict = {}
>>> for i in new_list:
...   new_dict[i[0]] = i[1]                #字典賦值，左邊為key，右邊為value
...
>>> new_dict
{'key3': 'value3', 'key2': 'value2', 'key1': 'value1'}
