In this lesson, you've learned about the common object types that you were already using before, so integer numbers that don't have a decimal point. Floats, which are numbers with a decimal point strings, which is text surrounded in quotes, and Boolean true or false object types. You've also learned about types of objects that help you organize other objects in your code, so lists which are contained in square brackets and are in a specific order and are able to contain multiple duplicates of the same values. You've also learned about sets, which are unordered and contain only unique values. You've learned about tuple, which are kind of like lists, but they're contained in parentheses and they are immutable. They're unchangeable. And you've also learned about dictionaries, which contain key value pairs. You've learned how to create these object types, and you've learned how to manipulate them.
