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
Is it bad if i barely understand anything in this comment?
Quite bad actually, since most of this stuff is not specific to c#, and are just basic programming concepts. This leads me to believe that your python experience is "coby and paste stuff in until it looks like it works", and you never took the time to understand what the code does.
Most probably, yes. A lot of these are fundamental concepts of most modern object-oriented languages that I am familiar with. It may be worth refreshing your basic programming skills/concepts with a book you like. There are plenty available online for free in C#, Java, C++, Go, etc.
Refreshing what? I don't have anything to refresh here. I only have experience with scripting languages, which are not object oriented at all
Python is an object oriented language.
This is going to sound harsh but... You need to take an intro to programming course.
I didn't know what your doing in Python, but you've not learned to program in Python. Maybe just copy pasting or making small changes to existing stuff? Working in a specific framework? Are you writing code from scratch?
You need to understand datatypes (a concept Python tries to hide from you and imo does a disservice to novices), structures, conditional is, loops, etc. These concepts aren't language specific.
Yes, i write from scratch in python, but only basic things. The most advanced are reading from a file and defining an own function. I'm in a programming course already
I wouldn't say it's that bad, it probably means you lack vocabulary rather than anything else.
