Detailing Official String Representation With .__repr__()
00:00
Now let’s get into developer-friendly string representations. The __repr__(), or represent method in Python is used to define the official string representation of an object and show the way the object is constructed in code, mainly for developers and debugging purposes.

Since this is the official representation, let’s do return f" for format, and you need to include the name of the class, so Storage( ), you need the value so in curly brackets, .self.value, comma, and you also need to include the units and you need to make sure that this will be a string.
