在python2.4前,sorted()和list.sort()函数没有提供key参数,但是提供了cmp参数来让用户指定比较函数。此方法在其他语言中也普遍存在。 在python3.0中,cmp参数被彻底的移除了,从而简化和统一语言,减少了高级比较和__cmp__方法的冲突。 在python2.x中cmp参数指定的函数用来进行元素间的比较。此函数需要2个参数,然后...

#Python内置的sorted()函数就可以对list进行排序:print(sorted([34,5,7,2,8,13]))print('---')#sorted()函数也是一个高阶函数,它还可以接收一个比较函数来实现自定义的排序。 # 比如,如果要倒序排序,我们就可以自定义一个reversed_self函数 # 传入自定义的比较函数reversed_self,就可以实现倒序排序 defreve...
Python list 内置 sort() 方法用来排序,也可以用 python 内置的全局 sorted() 方法来对可迭代的序列排序生成新的序列。 1 基本形式 列表有自己的 sort 方法,其对列表进行原址排序。元组不行,元组不可修改 >>> a = [3,6,1,8,0,5,7,9,2,4] ...
In the next section, we’ll discuss this key parameter more deeply.Sort a List of Strings in Python Using the Sorted FunctionWhile lists have their own sort functionality, Python exposes the sort functionality with a separate function called sorted which accepts an iterable. In other words, ...
list.sort() and sorted() added a key parameter to specify a function to be called on each list element prior to making comparisons. (从Python 2.4开始,list.sort() 和 sorted() 都添加了key参数用来指定对每个元素做比较的函数) AI检测代码解析 ...
