首先是基础配置,编写一个简单的Python脚本来完成这个功能: # 反转字符串的递归函数defreverse_string(s):iflen(s)==0:returnselse:returns[-1]+reverse_string(s[:-1])# 测试反转函数input_string="Hello, World!"output_string=reverse_string(input_string)print(output_string) 1. 2. 3. 4. 5. 6. ...
下面给你整理几种：使用切片defreverse_string(s):returns[::-1]使用递归defreverse_string(s):iflen...
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 to 0, the string is returned. If not equal to 0, the reverse function is recursively called ...
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] ...
Leetcode 344:Reverse String 反转字符串 公众号:爱写bug Write a function that reverses a string. The input string is given as an array of characterschar[]. Do not allocate extra space for another array, you must do this bymodifying the input array in-placewith O(1) extra memory. ...
The [::-1] syntax in the above code tells Python to slice the entire string and step backward by -1, which effectively reverses the string. Reversing a String Using the reversed() Function Another way to reverse a string in Python is by using the reversed() function. The reversed() fun...
Write a Python program to reverse a string. Sample String:"1234abcd" Expected Output:"dcba4321" Sample Solution-1: Python Code: # Define a function named 'string_reverse' that takes a string 'str1' as inputdefstring_reverse(str1):# Initialize an empty string 'rstr1' to store the reve...
defreverse_string1(s):"""Return a reversed copyof `s`"""returns[::-1]>>>reverse_string1('TURBO')'OBRUT' 新手第一次遇到列表切片时可能很难理解列表切片。 我觉得使用Python的切片功能来反转字符串是一个不错的解决方案,但是对于初学者来说可能很难理解。
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] print(reversed_string) # nohtyP ...
