Write a Program That Takes in a Line of Text as Input and Outputs That Line of Text in Reverse. The Program Repeats Ending When The User Enters Done Done Or d For The Line of Text

In this article you will learn a program that keeps accepting a line of text until the user enters “done”, then finally outputs the given line of text in reverse order.

Let's try to solve this using the Python program.

 

 

 

Write a Program That Takes in a Line of Text as Input, and Outputs That Line of Text in Reverse. The Program Repeats, Ending When The User Enters Done, Done, Or d For The Line of Text

Let's use an infinite while loop and inside the while loop, take a string variable and ask a user to enter a text.

Once the user enters a text,  check if the text is equal to “done” /”d” If this is true then  print an exit message and break the infinite while loop.

while True:
   text = input("\nEnter a Text : ")
   if text.lower() == "done" or text.lower() == "d":
       print("Exiting the Program Bye !!")
       break
   print("Text in Reverse is... ")
   print(text[::-1])

Outside the if statement reverse the text and print the reverse of a text.  I will be using a string slicing method to reverse a text using [::-1] as shown below.




Python Program
==========================
while True:
   text = input("\nEnter a Text : ")
   if text.lower() == "done" or text.lower() == "d":
       print("Exiting the Program Bye !!")
       break
   print("Text in Reverse is... ")
   print(text[::-1])





Output
===================
Enter a Text : hello world
Text in Reverse is...
dlrow olleh

Enter a Text : i love python
Text in Reverse is...
nohttp evol i

Enter a Text : code with tj
Text in Reverse is...
 jt htiw edoc

Enter a Text : done
Exiting the Program Bye !!




Output
================
Enter a Text : are you busy ?
Text in Reverse is...
? ysub uoy era

Enter a Text : coding !!!
Text in Reverse is...
!!! gnidoc

Enter a Text : d
Exiting the Program Bye !!




Conclusion
=================
In the above Python program we are using an infinite while loop to keep asking a user to enter the text until done is entered.  execute the above Python program by providing random text as input to the program and note down the results.
