This homework is due in next lesson. Make sure you have written your homework clearly in your planner.

If Statements What will this code do? ## is used to create comments which are ignored by Python but make the code easier to understand. If Statements What will this code do? if is used to decide if an action is going to be followed. It ends with a : symbol.
