There is no built-in function to reverse a String in Python. The fastest (and easiest?) way is to use a slice that steps backwards,-1. ExampleGet your own Python Server Reverse the string "Hello World": txt ="Hello World"[::-1] ...
This article explains how to reverse a String in Python using slicing.There is no built-in string.reverse() function. However, there is another easy solution.Use Slicing to reverse a String¶The recommended way is to use slicing.my_string = "Python" reversed_string = my_string[::-1] ...

原理是:This is extended slice syntax. It works by doing [begin:end:step] - by leaving begin and end off and specifying a step of -1, it reverses a string. 切片介绍:切片操作符中的第一个数(冒号之前)表示切片开始的位置,第二个数(冒号之后)表示切片到哪里结束,第三个数(冒号之后)表示切片间隔...
Yes. However, your reversed string should not contain leading or trailing spaces. How about multiple spaces between two words? Reduce them to a single space in the reversed string. fromcollectionsimportdequeclassSolution(object):defreverseWords(self,s):""":type s: str:rtype: str"""ifs==''...
