Loop Exercises

Exercise 1
Write a Python program that asks the user to enter a number that is greater than 0. The function will keep on asking the user for the number until it is valid. The function will return the number.
Exercise 2
Write a Python program that asks the user to respond by 'Y', 'y', 'yes', 'YES' or 'N', 'n', 'no', 'NO'. The function keeps on asking until the user enters the correct information. The function will return True if the user entered Yes, and False otherwise.
Exercise 3
Write a Python program that reads strings of characters until it finds the string "THE END.", in which case it stops.

The program will count how many times the word "mother" appears in all the strings entered.

Exercise 4
Write a program that reads a character for playing the game of Rock-Paper-Scissors. If the character entered by the user is not one of 'P', 'R' or 'S', the program keeps on prompting the user to enter a new character.
Make the program accept inputs until one player's score is more than 3 points ahead of the other.
