The first difference that I would point out is c# use of static typing, where python is dynamic. This author is using the var keyword to avoid specifying a type for variables. The type is, instead infered by the code that follows the equals sign.

The next main difference is the use of whitespace. Python is very whitespace aware, it uses indentation and line breaks to organize code. C# is whitespace agnostic in most cases and separates blocks of code using curly braces {…}, statements must end with a semicolon;

In C# collections are organized by how the data is accessed and whether elements can be added or removed. Arrays are initialized with a set of items and can’t be made longer, a List can be added to and can be removed. The key point is that all items in a collection are of the same type.

Complex objects (that have properties and methods) can be structs, classes, or records but they all basically do the same thing and interact in the samish way. You have to use the new keyword to make a new instance.

Classes and records can inherit from another where as structs cannot. Properties must have a type, methods must return a type or void. Method parameters must be typed, when calling a method the provided parameters must be of the proper type.

An interface describes requirements an implementing class, record or stuct must meet (i.e. properties and methods). You can’t make a new interface, it’s more of a qualification.

I hope this helps some
