The original string is : Geeksforgeeks The reversed string(using recursion) is : skeegrofskeeG Explanation :In the above code, string is passed as an argument to a recursive function to reverse the string. In the function, the base condition is that if the length of the string is equal ...
前段时间看到letcode上的元音字母字符串反转的题目,今天来研究一下字符串反转的内容。主要有三种方法: 1.切片法(最简洁的一种) #切片法 def reverse1(): s=input("请输入需要反转的内容:") return s[::-1] reverse1() #运行结果 In [23]: def reverse1(): ...
We have a string, "Hello World", which we want to reverse: The String to Reverse txt ="Hello World"[::-1] print(txt) Create a slice that starts at the end of the string, and moves backwards. In this particular example, the slice statement[::-1]means start at the end of the st...
