How do I grasp OOP concepts in Python?

You might want to start with a simple project tutorial on YouTube. Try copying the method that the instructor uses, and once you feel comfortable, recreate a similar project on your own while adding your twists. This technique can be really effective!

A great way to understand OOP concepts is by doing a project. Have you thought about creating a school management system? It could include features for teachers, students, and parents. It'll give you hands-on experience with classes and objects!

OOP felt overwhelming for me too, until I built a simple class for a `Dog` with methods like `bark()` and an attribute for `age`. Working with a simple, specific class really clicked things into place for me and I think a similar approach might work for you too!

Regarding using 'self', it's basically a reference to the instance of the class you're working within. When you define class methods, remember to include 'self' as the first parameter, but you don’t need to include it when calling the method. Parameters can be passed during initialization or to other methods just like function parameters. Here’s a quick example:

```python
class Line:
def __init__(self, length=30): # Optional parameter
self.length = length
self.info()

def info(self):
print(f"Line length: {self.length}")

def setLength(self, length): # Required parameter
self.length = length
self.info()

line_a = Line()
line_b = Line(length=20)
line_a.info()
line_b.info()
line_a.setLength(10)
```

So, in short, OOP is like structs but with functions. Understanding this relationship could make things clearer!
