Python 字典 items() 方法以列表形式（并非直接的列表，若要返回列表值还需调用list函数）返回可遍历的(key, value) 元组数组。
>>> D = {‘Google‘: ‘www.google.com‘, ‘Runoob‘: ‘www.runoob.com‘, ‘taobao‘: ‘www.
taobao.com‘}
>>> print(D.items())
dict_items([(‘Google‘, ‘www.google.com‘), (‘Runoob‘, ‘www.runoob.com‘), (‘taobao
‘, ‘www.taobao.com‘)])
for 循环
>>> for k,v in D.items(): ... print(k,v) ... # 执行结果 Google www.google.com Runoob www.runoob.com taobao www.taobao.com
