Use Slicing to reverse a String¶ The recommended way is to use slicing. my_string="Python"reversed_string=my_string[::-1]print(reversed_string)# nohtyP Slicing syntax is[start:stop:step]. In this case, both start and stop are omitted, i.e., we go from start all the way to the...
# Using slicing to reverse a string my_string = 'Hello, World!' reversed_string = my_string[::-1] print(reversed_string) The [::-1] syntax in the above code tells Python to slice the entire string and step backward by -1, which effectively reverses the string. ...
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
Userange()to Reverse a List in Python range()is a Python built-in function that outputs a list of a range of numbers. range(start,stop,step) This function has 3 arguments; the main required argument is the second argumentstop, a number denoting where you want to stop. There are 2 opt...
In all of the methods described above, we have created a new list to store the value of the original list in reversed order. Now we will see how we can reverse a list in place i.e. how we can reverse the same list which will be provided to us as input. ...
1. Python Slice [::-1] In Python, we can use[::-1]to reverse a string, akaextended slice. The below is the slice syntax: string[start:stop:step]Copy start– Start position, default is 0. (include this string) stop– Stop position. (exclude this string) ...
