1 2 3 4

string_data=input("Enter data you want to reverse") result=string_data[::-1] print("The string data you entered is :", string_data) print("The reversed string is:", result)

  2nd way: Using reversed() function:

Python provides inbuilt function reversed()

It returns reversed object and you can use join() method of strings to get your required output form reversed object.

1 2 3 4 5 6 7

string_data=input("Enter data you want to reverse") reversed_object=reversed(string_data) print("The string data you entered is :", string_data) for character in reversed_object: print(character,end='') print() print(type(reversed_object))

3rd way : Using While loop:

1 2 3 4 5 6 7 8

string_data=input("Enter data you want to reverse: ") result="" i=len(string_data)-1 while i>=0: result=result+string_data[i] i=i-1 print("The string data you entered is :", string_data) print("String data after reversal: ", result)
