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 ...
Thus, you can reverse the string using the [::-1] operator. Reverse string using [::-1] print('Python'[::-1]) # nohtyP Python Slice Operator Syntax Slice() returns a slice of the object for a specified sequence (string, tuple, list, range, or bytes). Slicing allows you to ...
Original String is: PythonForBeginners Reversed String is: srennigeBroFnohtyP Reverse string using for loop To reverse a string using a for loop, we will first calculate the length of the string. Then, we will create a new empty string. Afterwards, We will access the string character by ...
Using a for loop, each character is pushed onto the stack. As the stack follows LIFO, popping elements from it will yield the characters in reverse order, which are stored in a new character array. Finally, the reversed string is created using the String constructor and displayed. Reverse a...
video • Python 3.9—3.13 • June 12, 2023 How can you loop over an iterable in reverse?Reversing sequences with slicingIf you're working with a list, a string, or any other sequence in Python, you can reverse that sequence using Python's slicing syntax:...
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 the input string 'str1'index=len(str1)# Execute a while loop until...
As you can see in the above code snippet, we're creating a variable strReverse that contains an empty string (with no spaces in it). The next thing we're doing is we're looping over the string that needs to be reversed using the for loop. The initial value of I in the loop is ...
There can be multiple approaches to traverse a Python list in reverse order. Some of the approaches are as follows:Let's discuss each approach in details:1. Using list slicing The easiest and simplest approach for traversing a Python list is that - You can use list slicing. Use negative ...
