sort() >>> fruits ['apple', 'apple', 'banana', 'banana', 'grape', 'kiwi', 'orange', 'pear'] >>> fruits.pop() 'pear' 列表作为栈使用 栈的特点是后进先出,而列表为我们提供了append和pop方法,所以使用列表来实现栈是非常简单的: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 >>> ...

本文主要是对 Problem Solving with Algorithms and Data Structure using Python一书中的排序算法大概总结,做个记录。Bubble Sort 如上图所示,Bubble Sort 比较相邻的两个数,若大小顺序不符合,则交换。假设共…
sort:对列表进行inplace排序,可接受一个key参数指定排序规则,接受reverse参数明确是正序还是逆序 reverse:对列表进行inplace翻转 copy:对列表进行浅拷贝 列表的这些方法中,除了clear用的较少外,其他都是常用接口,需要注意的是虽然pop、remove、index和insert操作语法比较类似,但存在一个最大的不同是:insert接受的索引参...
Then, we sort the list by using the sort method of the list. It is important to understand that this method affects the list itself and does not return a modified list - this is different from the way strings work. This is what we mean by saying that lists are mutable and that ...
