Transitioning from Python to Java

To be honest, me, a C/C++ developer once had issues with grasping even such basic concept as pointers. You learnt Python and you enjoy it. That's good. You already have one language in your portfolio. Regarding OOP - if you use classes in Python it is already a part of OOP. (Of course, you need to be able to use e.g. inheritance in Python) You want to code in English, so you prefer something with easy syntax, so maybe JS? Regarding JVM - you should not care about it until you are senior-ish dev. Java philosophy is "run everywhere". If you screw up you JVM, it will just run slower and eat your RAM. ----- OK, I wrote a lot text, so let's summarize: Not being able to write a linked is not a big deal for a beginner You really must understand OOP. Without it you won't get your first job. You can do learn it in Python Btw, Python is not that great as the sole language, market-wise. More on reddit.com

how to switch from java to python?

It isn't as hard as you might think. If you know java you know the core fundamentals of coding that are basically the same in every language. Once you know what you need to do, it's basically looking up syntax, libraries, etc. My advice is don't stress about it, take it slow. Python is actually pretty user friendly! More on reddit.com

Should I switch to Python from Java

Inputting is a struggle too, because ... solving problems in LeetCode with Java too, but having to write so many extra stuff is tiring and it wastes a lot of time in technical interviews. I am currently working on a project and I use Python with it.... More on reddit.com

Before moving from Java to Python, what does Python lack that Java has? ( Think about enterprise application)

Python has analogs for almost everything that Java has. There are some differences though. Off the top of my head: Obligatory OOP. Python classes are optional. Access modifiers. Python has no analogs for public/private/protected. All classes and methods are public. Although there are conventions governing 'private' methods, there is nothing stopping you from using them in a public context. Packages. Python does allow modules, but the Java 'package' concept is missing. Typing. Python has no compile-time type checking. You can freely mix types and change types of variables at runtime. I would strongly suggest you look up Python type hints and start using them from day one. It will greatly aid debugging. Abstract classes. Python has an ABC (abstract base class) module which does almost the same thing, but there are differences. Interfaces. No such thing in Python. Since Python allows multiple inheritance, interfaces can be simulated with abstract base classes. Generics. Since there is no compile-time type checking, the concept of generics doesn't really apply. Again, you can use type hints to document generics, but they won't be enforced. Lambdas. Python does have lambdas, but they are limited to single expressions, unlike the code blocks that Java allows.
