#exercise8 Printing

The difference between printing "%r" and "%s" is that "%r" is good for debugging because it shows the raw data of the variable, while the other symbols are used to show the output to the user.
Formatter= "%r%r%r%r"
Print formatter% (1,2,3,4)
Print Formatter% ("one", "one", "one", "three", "four")
Print Formatter% (
"That's could type up right.",
"But it didn ' t sing.",
"So I said Goodnight.")
