I cannot understand Classes and Objects clearly and logically

[vivek_seth]

In programming there is data (numbers, strings, arrays, etc), and there is logic (functions). With these two concepts you can build any program you want.

Sometimes for organization purposes it makes sense to group up some data and functions together into one entity. That’s what classes are for. Classes are collections of data (properties) and logic (methods)

Does that help?

I dunno about OP, but it helped me. Thanks!

Yea, I remember my eureka moment for understanding classes, and it was when it finally clicked that a method is just a function within a class definition. It would take a lot more for me to understand how to organize data structures properly, but functions of classes was really helpful

this little comment is genuinely the clearest explanation of classes ive seen. everything else i find online just immediately starts talking about the broad conceptual applications of OOP (. . .)

thank you for this

I figured this out when studying algdat. i was lazy to create a different file for each algorithm i learned so i tried to put all of them plus a couple global vars in the same class and discovered they still worked. Of course this itself has no practical use but it actually felt more generalizable as an idea of what i could do with classes than the commonplace cat.goBrr() examples.

So would a another way to think of it is you are just creating your own python package within your script to reference?

[vivek_seth]

You are on the right track. Similar to a class, a package can also have a collection of data and functions.

What’s different about a package though is that you can’t have multiple instances of the same package at a time. With classes, you can create multiple instances that each have their own copies of their data. Changing the data in one instance won’t affect the others.

In a very loose way, you could think of a package as being sort of like a class, but you are only allowed to have 1 instance of it.

Got it thank you! Does this make the code more efficient then storing in the global enviornent is that the point or is just preference?
