Object-Oriented Programming Summary-Python,-python
All things are objects. The natural environment gives us endless imagination, and the idea of object-oriented programming comes from nature. In nature, classes and objects are everywhere. For example: birds and sparrows, fish and carp ...... birds are the generic names
lacks the repl (R, Python, and Scala) required for interactive development. I've seen 10 lines of Scala-based spark code quickly become a perverted 200-line code written in Java, as well as huge types of statements that occupy much of the screen space. However, the new lambda support features in Java 8 can be helpful in improving this situation. Java is never as compact as Scala, but Java 8 does make development in Java less painful.As for REPL? Well

There is no independent function in C #, only the concept of a class (dynamic or Static) method, which refers to a member of a class that performs calculations or other behavior. In Python, you can define a dynamic or static member method of a class in a way similar to C #, because it supports full object-oriented programming as it does in C #. You can also write Python
