In the exercise above the code defines a function named "string_reverse()" that takes a string as input and returns its reversed version using a while loop and string manipulation. The final print statement demonstrates the result of calling the "string_reverse()" function with the input strin...
Reverse the string using the Python slice operator The slice operator [::] extracts a portion of a string from the provided string. But if you pass -1 as the last parameter, the slice operator will work in reverse order. If you do not pass the first two parameters (start and end posit...
# Program to explain reverse string# Using while loop# Define a functiondefreverse_while(string):# Declare a string variablerstring =''# We will calculate string length# And subtract 1 because string index start with 0length =len(string) -1# We will run the loop with last string indexwhi...
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:...
In this tutorial, we have implemented a code to find the minimum number of steps required to reverse the given string by swapping the adjacent characters only. We have used the nested while loop and reversed the copy of the given string to find the solution. The time complexity of the abov...
In summary, Python provides a simple way to reverse a list by making use of the functionreversed(). You also can reverse a list manually by looping it in afororwhileloop. Python also has an easy method of reversing a list in a single line if you are comfortable using the slice operato...

2. Using reversed() method You can also usereversed()method while iterating over the list elements. It returns a reverse iterator and it does not modify the given list. Example # Traverse a Python list in reverse order# Using reversed() method# Define a listlist1=[10,20,30,40,50]# ...
It has to subtract 1 because the indexes of, for example, a 5-character length string like 'Hello' are from 0 to 4. This integer is then stored in the i variable. Introducing the while Loop Line 8 is a type of Python instruction called a while loop or while statement: 8. while i...
