General Type Categories

Now that we’ve explored the first of Python’s collection objects, the string, let’s pause to define a few general type concepts that will apply to most of the types we look at from here on. With regard to built-in types, it turns out that operations work the same for all the types in the same category, so we’ll only need to define most of these ideas once. We’ve only examined numbers and strings so far, but because they are representative of two of the three major type categories in Python, you already know more about several other types than you might think.
