Strings may contain the format characters you have discovered so far. You simply put the formatted variables in the string - and then a % (percent) character - followed by the variable. The only catch is that if you want multiple formats in your string to print multiple variables - you need to put them inside ( ) (parenthesis) separated by - (commas). It's as if you were telling me to buy you a list of items from the store and you said - "i want milk - eggs - bread - and soup." Only as a programmer we say - "(milk - eggs - bread - soup)."
