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 to 0, the string is returned. If not...
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] ...

# Using the reversed() function to reverse a string my_string = 'Hello, World!' reversed_string = ''.join(reversed(my_string)) print(reversed_string) In the above code, we first pass the original string to the reversed() function, which returns a reverse iterator. We then use the joi...

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 reversed stringrstr1=''# Calculate the length of...
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 ...
The combination of above function can be used to perform this particular task. In this, we reverse the string in memory and join the sliced no. of characters so as to return the string sliced from rear end. # Python3 code to demonstrate working of ...
The reversed() function allows us to process the items in a sequence in reverse order. It accepts a sequence and returns an iterator.Its syntax is as…
join(reversed_chars) string = "hello" reversed_string = reverse_string(string) print(reversed_string) # 输出: 'olleh' 9.7 转换为列表排序或逆序 将字符串排序或逆序通过先将其转化为列表是一种常见的做法,因为字符串在 Python 中是不可变的,而列表是可变的。所以可以先将字符串转化为列表,可以很灵活地...
