Hi Tim,
You have a couple of problems with your return string which is causing the issues.
You have set {0} when instead you just want {} as you only need to define alphanumeric values when unpacking data
You have left off the full stop at the end of the string.
python
return "We're open from {} to {}.".format(self.open, self.close)
Hope that helps. Answer from Chris Shaw on teamtreehouse.com

Class and Object β Python Numerical Methods
For example, student1.name is βSusanβ and student2.name is βMikeβ. But when we print out the class attribute Student.n_instances after we created object student2, the one in the student1 changes as well. This is the expectation we have for the class attribute because it is shared across all the created objects. Now that we understand the difference between class and instance, we are in good shape to use basic OOP in Python.

What exactly is an object in Python?
An object is a data structure that can have properties and methods. A property is a piece of data like a string, integer, or another object. Think of it as a variable within the variable. A method is a function built into the object which it can be called to carry out. Like any other function it takes arguments but it also has access to any of the object's properties. In Python an object is defined by a class, which says what properties objects of that type will have and what methods they can execute. This is how most object oriented languages do it, with the exception of Javascript, which uses an entirely different framework. From a class one can create multiple instances of an object. Each instance will have the same properties, but set to different values. Each instance will be able to do the same methods. For example imagine a Student object. It would have a name, age, grade, and so on. It could have the moveUp() method, which would increase the Student's grade. A file object is just a kind of object Python can create that allows it to do things to a file, like read from it or write to it. A number is technically an object in Python. This is not the case in all object oriented languages. But it's better thought of as a "primitive," meaning the stuff that other objects can be made of. A number only has one piece of data, the number itself, and doesn't have any built in methods (I think). This barely scratches the surface of object oriented programming. Google "python oop" and read various resources and you'll learn a lot more. More on reddit.com
introspection - How do I look inside a Python object? - Stack Overflow
After playing around Python a little bit, I feel like Python does not encourage us to read objects's content. Take JS for example: just a simple act of calling an object will list all the content of it, while in Python if an attribute is also an object, it doesn't write down that sub-object.

What is meant by "everything in python is an object"
Every function is an object, as well: >>> def func(): ... return True >>> func.__name__ 'func' I access the class attribute __name__ on the newly created function, to demonstrate it has attributes just like an object. More on reddit.com

There are also special attributes in it that begin with double underscores __. For example, __doc__ gives us the docstring of that class. As soon as we define a class, a new class object is created with the same name.

Python Object And Class (Tutorial With Examples)
July 6, 2024 - Python will automatically include it when the function is called. Like we mentioned earlier, a class is just a blueprint which doesnβt occupy any memory until it is instantiated. The instance of the class is called object. Creating object is same as declaring a variable of class type and we do it simply by calling the class and assigning it to an object (variable). For example, we have created a class of car and letβs create an object for this class.

You cannot instantiate a WindowsPath when running on Unix, but you can instantiate PureWindowsPath. You want to make sure that your code only manipulates paths without actually accessing the OS. In this case, instantiating one of the pure classes may be useful since those simply donβt have any OS-accessing operations. ... PEP 428: The pathlib module β object...

r/learnprogramming on Reddit: What exactly is an object in Python?
April 29, 2022 -
Thinkpython book by Allen Downey defines objects as something a variable can refer to to which he adds "object" and "value" can be used interchangeably. So, if my understanding serves me well, a variable stores a value, for e.g. x = 5, does that imply 5 is an object as well?
Then, I come across "file object" which is known to bear reference to a file. Maybe I'm overcomplicating things that's why I can't seem to grasp these concepts.

An object is a data structure that can have properties and methods. A property is a piece of data like a string, integer, or another object. Think of it as a variable within the variable. A method is a function built into the object which it can be called to carry out. Like any other function it takes arguments but it also has access to any of the object's properties. In Python an object is defined by a class, which says what properties objects of that type will have and what methods they can execute. This is how most object oriented languages do it, with the exception of Javascript, which uses an entirely different framework. From a class one can create multiple instances of an object. Each instance will have the same properties, but set to different values. Each instance will be able to do the same methods. For example imagine a Student object. It would have a name, age, grade, and so on. It could have the moveUp() method, which would increase the Student's grade. A file object is just a kind of object Python can create that allows it to do things to a file, like read from it or write to it. A number is technically an object in Python. This is not the case in all object oriented languages. But it's better thought of as a "primitive," meaning the stuff that other objects can be made of.

Say, you have a store called Doggo World and they offer specials for whoever signs their dog up. In the form, you have to put in some information. Dog's name Dog's breed Dog's age Dog is chipped (true/false) Master's name Master's phone number These 5 pieces of information are called different things in different languages such as fields, member variables, instance variables. This information that should be printed out in a form can be called a class which is like a recipe. A recipe is not a dish until you cook it. A class is not an object until you create it. Another analogy is a book has a bunch of words. Those words for a book form a "class", and the actual book is an object. You can have many books but they are considered the same. You don't need a class but many OO languages use them as the basis to create objects. An object generally has several features. First, the fields (we'll call them fields) are usually inaccessible for direct access. This is known as encapsulation. This is mostly to prevent direct access to the data. The reason for this is typically data validation. If the field contained a test score, you might want to ensure the values are between 0 and 100. However values generally have a type (like int) and that has a much larger range than 0 and 100. In this case, maybe you want to make sure that the phone number has a valid format. Instead, access is done though methods called getters/setters and possibly other methods that do other things. So far, that makes what you've done "object based". I won't go through more details to discuss inheritance but some argue that this is a necessary feature of OO programming. In Java, it's not used much because of interfaces which I also won't go through much. As far as whether 5 is an object, it depends on the language. Usually an object has methods on it. In Java, there is a primitive type called int where 5 is not an object, and one where it is Integer which is an object. It might start off as not an object, but Java does something called autoboxing which converts and int to an Integer or an Integer to an int. In some languages, everything is an object, so 5 can be an object. I think in Python it probably is an object as Python numbers can grow in size past the largest value an int can have. For files, typically, the File object references a location of a file, but you still need to do operations like opening a file, closing a file, reading and writing from a file. So it doesn't really represent the file's content, but you can use it to access the contents through methods. It represents some information about where this file should be located (there may not be a file there, but that's OK).

In a sense the set of attributes of an object also form a namespace. The important thing to know about namespaces is that there is absolutely no relation between names in different namespaces; for instance, two different modules may both define a function maximize without confusion β users of the modules must prefix it with the module name. By the way, I use the word attribute for any name following a dot β for example, in the expression z.real, real is an attribute of the object z.

Python has a strong set of introspection features.
Take a look at the following built-in functions:
type()dir()id()getattr()hasattr()globals()locals()callable()
type() and dir() are particularly useful for inspecting the type of an object and its set of attributes, respectively.
