Python 字典 items() 方法

Posted 2021-01-13 minger_lcm

 

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
