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]print(txt) Try it Yourself » ...
If you don't mind overwriting the original and don't want to use slicing (as mentioned in comments), you can call reverse() method on the list. >>> num_list = [1, 2, 3, 4, 5]>>>num_list.reverse()>>>num_list [5, 4, 3, 2, 1] If you want to loop over the reversed ...
In this Python tutorial, I will explain how toreverse a list in Pythonusing while loop and for loop. The reverse of data in the list is used in data processing or any other fields where the order of operations needs to be reversed in functional programming contexts. You can also use the...
The easiest and fastest way to reverse a string in Python is to use the slice operator [start:stop:step]. When you pass a step of -1 and omit the start and end values, the slice operator reverses the string. A more verbose, but readable (and slower) version of the string reversal ...

Loops can also be used to reverse a string in Python - the first one we'll consider is theforloop. We can use it to iterate over the original string both ways - forwards and backward. Since we want to reverse a string, the first thing that comes to mind is to iterate over the str...
