7)其他语言普遍使用的排序方法-cmp函数 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...
Thesorted()method accepts another optional parameter- thekeyfunction. For example, sorted(iterable, key = len) Here,lenis Python's built-in function that counts the length of an element. In this case, thesorted()method sorts the list based on the length of the element. For example, ...

一、Python的排序 1、reversed() 这个很好理解,reversed英文意思就是:adj. 颠倒的;相反的;(判决等)撤销的 print list(reversed(['dream','a','have','I'])) #['I', 'have', 'a', 'dream'] 1. 2、让人糊涂的sort()与sorted() 在Python 中sorted是内建函数(BIF),而sort()是列表类型的内建函数...
