Representing Objects as Strings
00:00 When you create a new class, it’s important to think about how its object will look when you print them. There are two ways to do this. The user-friendly representation and the developer-friendly representation.
00:13
Let’s start with the user-friendly one. The __str__() special method returns a human-readable string representation of the object at hand. Python calls this method when you call the built-in str() function, passing an instance of the class as an argument, and also when you use the instance as an argument to the print() and format() functions.

Let’s go back to the Storage class and implement the __str__() method to return a string that indicates both the value and the unit of the instance.
00:53
So far, this is how the Storage class looks like. So let’s go ahead and add a __str__() magic method here. def __str__() passing self and returning f for format, and you want to return the value, so {self.value} space in between and {self.unit}.

Alright, now let’s run the code and see what happens when you print storage_size.
01:32 There you go. You get 512 GB which is exactly what you wanted.
