Python String doesn’t have a built-in reverse() function. However, there are various ways to reverse a string in Python. Show
1. How to Reverse a String in Python?Some of the common ways to reverse a string are:
1.1) Python Reverse String using Slicing
If you run above Python script, the output will be:
1.2) Reverse String using For Loop
Output: 1.3) Reverse a String using While Loop
1.4) Reverse a String using join() and reversed()
1.5) Python Reverse String using List reverse()
1.6) Python Reverse String using Recursion
2. Best Way to Reverse a String in PythonWe can reverse a string through multiple algorithms. We have already seen six of them. But which of them you should choose to reverse a string. We can use timeit module to run multiple iterations of these functions and get the average time required to run
them. All the above functions are stored in a python script named The below table presents the results and slowness of an algorithm
from the best one.
3. SummaryWe should use slicing to reverse a string in Python. Its code is very simple and small and we don’t need to write our own logic to reverse the string. Also, it’s the fastest way to reverse a string as identified by the above test executions. You can checkout complete python script and more Python examples from our GitHub Repository. 4. References
How do you reverse a list of strings in Python?In Python, you can reverse the items of lists ( list ) with using reverse() , reversed() , and slicing. If you want to reverse strings ( str ) and tuples ( tuple ), use reversed() or slice.
How do you reverse a list in a list Python?reverse() Method. Every list in Python has a built-in reverse() method you can call to reverse the contents of the list object in-place. Reversing the list in-place means won't create a new list and copy the existing elements to it in reverse order. Instead, it directly modifies the original list object.
Does Reverse () work on strings?reverse() works like reversing the string in place. However, what it actually does is create a new string containing the original data in reverse order.
Can you reverse strings in Python?Reverse string in Python using reversed() method
The reversed() returns the reversed iterator of the given string and then its elements are joined empty string separated using join(). And reversed order string is formed.
