Reading the changes in Python 3.1 , I found something... unexpected: 阅读Python 3.1中的更改后 ,我发现了一些意外……
The sys.version_info tuple is now a named tuple : sys.version_info元组现在是一个命名的元组 :
I never heard about named tuples before, and I thought elements could either be indexed by numbers (like in tuples and lists) or by keys (like in dicts). 我以前从未听说过命名元组,并且我认为元素可以通过数字(例如在元组和列表中)或通过键(例如在字典中)进行索引。 I never expected they could be indexed both ways. 我从未想到它们可以同时被索引。
Thus, my questions are: 因此,我的问题是:
