 First multi-line comments
 function get_key() : 	because of this fuction we were unable to close the game on the DISPLAY_SURF where we enter data
 						as it contains an infinite loop which goes on till a key is pressed(not just mouse click)
 						and mouse click is not a key event so it is undetected .Adding pygame.QUIT part in this function
 						solves the problem
