In this post, we will understand how dataclass behaves when they implement one of the most important object-oriented concepts: Inheritance. We have previously discussed what dataclasses are, how they behave, and their field functions. It is strongly suggested to go through those posts in detail...

Often when we’re using numbers, but also,occasionally, with other types of objects,we would like to do some type of randomness. 例如,我们可能想要实现一个简单的随机抽样过程。 For example, we might want to implement a simple random sampling process. 为此,我们可以使用随机模块。 To this end, ...

Parent or base classes create a pattern out of which child or subclasses can be based on. Parent classes allow us to create child classes through inheritance without having to write the same code over again each time. Any class can be made into a parent class, so they are each fully func...
