python中如何实现列表与字典的相互转换？

>>> ls = ['a','b','c']

>>> lt = [1,2,3]

>>> d = dict(zip(ls,lt))

>>> d

{'a': 1, 'b': 2, 'c': 3}

list2 = [['key1','value1'],['key2','value2'],['key3','value3']]

print(dict(list2))

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

dict={'name':'wsm',

      'age':'22',

      'sex':'female'}

print(list(dict))

print(list(dict.keys()))

print(list(dict.values()))

print(list(dict.items()))
