The Difference Between Junior and Senior Python Developers
Being a senior Python developer isn't about memorizing every function or writing complicated code.
It's about knowing how to:
Read documentation
Use existing libraries
Write clean and maintainable code
Leverage helpful tools
Build better projects
Junior developers ask: "How do I write this code?"
Experienced developers ask: "How can I solve this problem efficiently?"
You don't need to reinvent the wheel. You need to know when and how to use it.
Same Python. Same Developer. Better Experience.

Python learning really does feel like this.
Year 1: print("Hello World")
Year 2: Data structures, functions, OOP
Year 3: Debugging becomes a full-time skill
Year 4+: Real projects, automation, Data Science, AI
The funny part? The errors never completely disappear.
You just get better at understanding them.
Same learner. Different year. Bigger problems. Bigger skills. Bigger dreams.

Did you know Python supports multiple inheritance?
In Python, a class can inherit from more than one parent class, allowing it to combine attributes and methods from multiple classes.
One important concept to understand is MRO (Method Resolution Order) — Python uses it to determine which method should be called when multiple parent classes define the same method.
https://link.amazon/B0bc3nCpv
A powerful feature, but one that should be used thoughtfully to keep your code maintainable.
