Java™ has significant advantages over other languages and environments that make it suitable for just about any programming task.
The advantages of Java are as follows:
Java is easy to learn. Java was designed to be easy to use and is therefore easy to write, compile, debug, and learn than other programming languages.
Java is object-oriented. This allows you to create modular programs and reusable code.
Java is platform-independent. One of the most significant advantages of Java is its ability to move easily from one computer system to another. The ability to run the same program on many different systems is crucial to World Wide Web software, and Java succeeds at this by being platform-independent at both the source and binary levels.
Because of Java's robustness, ease of use, cross-platform capabilities and security features, it has become a language of choice for providing worldwide Internet solutions.
The advantage of Python is that there exists a lot of online courses on this popular programming language. It is a high-level universal language that has a huge community around it and allows you to build high-quality applications.
If you are looking for free educational materials, I can recommend the following tutorials:
1. Codecademy - learn python through interactive tutorials
2. Introduction to programming using Python 3 - very well written tutorial by Hans Petter Langtangen
3. A Byte of Python - free book on the Python language released under GNU Free Documentation License
I recommend reading each one of them, but if you only have a limited amount of time I advise you to start with the Codecademy tutorial. It is short and easy to understand, and it consists of material that will help you understand the basics of Python programming.
The second tutorial you can take is Introduction to programming using Python 3. This tutorial was made by Hans Petter Langtangen, which is very popular among beginner programmers. So if you are interested in learning Python step-by-step, this course will be useful for you.
It's also worth mentioning the website A Byte of Python. It's a free book on how to program in Python, and it has been written for both beginner and advanced programmers. The site was released under GNU Free Documentation License, so you can download it as an e-book.
If you want to learn it from scratch then I'd recommend you to read "python in easy steps" The reason why I love it is Because they use code examples in real language and they give you multiple screenshots of what each variable looks like when you create it and they also tell you how many times each variable is used. you will learn how to create a real-world program step by step. There is also an introduction to file handling at the beginning of the book which tells you what a program is and how to run it. I am also learning Python for the last few months and it is an amazing experience for me, and I found this post on the internet, this post(https://monovm.com/blog/python-cheat-sheet/) is about the python cheat sheet, which helps me a lot.
