In the below example, we have used the f-string inside a print() method to print a string. We use curly braces to use a variable value inside f-strings, so we define a variable ‘val’ with ‘Geeks’ and use this inside as seen in the code below ‘val’ with ‘Geeks’.The time complexity of this code is O(n), where n is the length of the input string. The str.maketrans() method has a constant time complexity as it simply creates a translation table, and the translate() method also has a linear time complexity as it loops through each character in the input string and performs the translation based on the table.
