classes for nicer syntax. There are special methods known as "dunder" methods. The "dunder" means "double underscore". These methods, like__eq__,__gt__, and__or__, allow you to use operators like==,>, and|with your class instances (objects). Let's see how they work with theA...
This segment looks at the machinery behind for-loops, including the distinction between something which could be used in a loop (an iterable) and something which is being used in a loop (an iterator), and how Python knows when there are no more items to use in a for-loop. Keywords Pyth...
Another thing@dataclassdoes behind the scenes is automatically create code for a number of common dunder methods in the class. In the conventional class above, we had to create our own__repr__. In the dataclass, the@dataclassdecorator generates the__repr__for you. Once a dataclass is cr...
and proves the very next value that is to be calculated. This is done by using the generator method called __next()__. (That istwounderscores before and after "next()". These are generally called "dunder methods" or "magic methods" in Python.) Let's look at an example using our pr...
