Given that the python class is so simple and compact, I decided to use the dynamic keyword in a more creative way, and embed the python directly in the C# code:. Defining a Class in Python Like function definitions begin with the keyword def , in Python, we define a class using the keyword class. In this example, Hand inherits __init__ from Deck , but it doesn’t really do what we want: instead of populating the hand with 52 new cards, the init method for Hands should initialize cards with an empty list. Its design philosophy emphasizes code readability, and its syntax allows programmers to express concepts in fewer lines of code than would be possible in languages such as C. This class provides very little in terms of data and behaviors (those behaviors it does provide are all double-underscore methods intended for internal use only), but it does allow Python to treat all objects in the same way. In Python, you could create a class Person and extend it with the child classes listed above, but you could not prevent someone from instantiating the Person class.
