Okay, before you go on, do some power poses. standing with your arms up or your legs spread for like 10 minutes can greatly improve your mood. if you're in a classroom though, and can't do that, I would recommend making sure you have good posture while waiting to go up, and keep a smile on your face the whole time! even long before you start. smiling can increase your happiness a whole lot, so make sure you do it! also before the presentation, make sure you drink plenty of water (a gallon a day for the average adult) and get enough sleep. when preparing for your presentation, don't try to memorize the words you're going to say, (especially not if you'll have a reference like a paper or a slideshow) but memorize the ideas you want to convey. if you've written a speech, don't practice the speech exactly, practice conveying the ideas in it without reading from it. The worst thing you can do during a presentation is just stand there and read. Make sure you make eye contact and don't speak in monotone, tell a story with your presentation, don't just give information. if you need help being confident, I would suggest listening to some of your favourite music or some inspiring speeches (which you can find real easy on google<span>) to make you feel good about yourself. If you are having troubles with stage fright, or being in front of people, the best thing I've ever done, is just pretend they aren't there. Pretend you're just talking to yourself in your bedroom, and it becomes a lot more easy to express yourself. and if none of that sort of stuff works, maybe take some nerve medicine, if you have it. </span>

while string not in {"Quit","quit","q"}:
string=input("Enter line to be reversed") #line of text will be entered
if string!="Quit" and string!="quit" and string!="q": #If quit is not entered
print("Reverse of line is : ")
print(string[::-1])
OUTPUT :
Enter line to be reversedThis code is in python language
Reverse of line is :
egaugnal nohtyp ni si edoc sihT
Enter line to be reversedHello world
Reverse of line is :
dlrow olleH
Enter line to be reversedquit
Explanation:In the above program, First a while loop is executed and checked if line of text is not 'quit', 'Quit' or 'q'. If condition is true, then loop is executed and in python any string or list can be traversed from end if step is given -1. Similarly line of text is accessed from the last element. If quit is entered, then the program will be broken out of the loop.
