>>> for card in accusation: # 或者写作for card in accusation.keys():
... print(card)
...
room
weapon
person
如果要对值而不是键进行迭代,可以使用字典的
values()
函数:
>>> for value in accusation.values():
... print(value)
...
ballroom
lead pipe
Col. Mustard
要想以元组形式返回键和值,可以使用
items()
函数:
>>> for item in accusation.items():
... print(item)
...
('room', 'ballroom')
('weapon', 'lead pipe')
('person', 'Col. Mustard')
可以一次性完成赋值。对于
items()
返回的每个元组,将第一项(键)赋给
card
,将第二
项(值)赋给
contents
。
>>> for card, contents in accusation.items():
... print('Card', card, 'has the contents', contents) ...

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.
