Python string library does’nt support the in-built “reverse()” as done by other python containers like list, hence knowing other methods to reverse string can prove to be useful. This article discusses severa

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 write clear, concise and readable code. Python slice() Syntax slice...
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 ...
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...
The input string "Java Program" is defined, and we convert it into a character array. 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. ...
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 the str.length - 1 i.e. the index of the exclamation mark character. After each interation we're decrementing the value of i. The loop...
JavaScript: Split a string into an array, reverse the array, then join it back into a string. Python: Utilize slicing ([::-1]) to quickly reverse the string. Java: Convert the string to a StringBuilder, call reverse(), and convert back to a string. C++: Employ built-in functions lik...
