my_string = 'this is John\'s ball'.
- \n is used to jump to a new line, Eg;
my_string = "Johns is a good boy\nbut he hates going to school."
the next set of the string after the '\n' character is displayed on the next line.
- \t is used to add a tab space to a string.
my_string = 'Jane is \thungry'
