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_str
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...
Original string: reverse Reverse string: esrever Explanation: In the exercise above the code demonstrates the use of a "reverse()" function that utilizes slicing ([::-1]) to reverse a given input iterable. It then applies this function to reverse both the string '1234abcd' and the string ...
Learn how to reverse a String in Python.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]print(txt) ...
There is no built-instring.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 ...
# Python code to reverse a string # using stack # Function to create an empty stack. It # initializes size of stack as 0 defcreateStack(): stack=[] returnstack # Function to determine the size of the stack defsize(stack): returnlen(stack) ...
1. list的reverse函数:反转一个list 2. string的join和spilt函数分别“从list串联出一个字符串(以该string对象为分隔符)”和“把字符串分割为list”,若spilt参数为空,默认以空格、tab、newline等空白符作为分隔符 3. re模块 为正则表达式模块。 re.split(r’\s+’,str)等价于str.split() ...

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...
def FirstReverse(str): # code goes here return str # keep this function call here print FirstReverse(raw_input()) 二、解法:切片 A simple way to reverse a string would be to create a new string and fill it with the characters from the original string, but backwards. To do this, we ...
