Python中元组的时间复杂度 [英] Time complexity of tuple in Python
本文介绍了Python中元组的时间复杂度的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
关于哈希(字典)和列表也有类似的问题,这里也有很多信息: http://wiki.python.org/moin/TimeComplexity
There is similar question about hash (dictionaries) and lists, also there is a good piece of info here: http://wiki.python.org/moin/TimeComplexity
但是我没有找到有关元组的任何信息。
But I didn't find anything about tuples.
The access time for
data_structure[i]
- 对于链表通常是O(n)
- 对于字典是〜O(1)
元组怎么样?
是链表的O(n)还是数组的O(1)?
What about tuple? Is it O(n) like for a linked list or O(1) like for an array?
推荐答案
列表和元组均为O(1)。它们在道德上都等效于整数索引数组。
It's O(1) for both list and tuple. They are both morally equivalent to an integer indexed array.
