-Tell people how to see the `type`:
 You can see that `a` and `b` are both instances of the `A` class by using the `type` function.

 ### Aside: Using Class to Hold Parameters
 
-We have been using objects and classes both internal to python (e.g. `list`) from external libraries (e.g. `numpy.array`).  Sometimes it is convenient to create your own classes to organize parameter, data, and functions.
+We have been using objects and classes both internal to python (e.g. `list`) from external libraries (e.g. `numpy.array`). Sometimes it is convenient to create your own classes to organize parameter, data, and functions.
 
 In this section we will reimplement our function using new classes to hold parameters.

-The `@dataclass` is an example of a python decorator (see [documentation](https://docs.python.org/3/glossary.html#term-decorator)).  Decorators take in a class (or function) and return a new class (or function) with some additional features.  In this case, it automatically creates the `__init__` function, allows for default values, and adds a new `__repr__` function which determines how the object is printed.
