Is Ruby better than Python?
Python is faster than Ruby, but they’re both in a category of interpreted languages. Your fastest language is always going to be one that’s compiled down to byte code or object code right on the computer. … It makes the development cycle a lot faster, but they are slower languages.
Is Ruby similar to Python?

Is Python an ooo?

Is Java 100% object oriented language?
JAVA supports primitive data type as it, byte, long, etc so Java is not fully object-oriented. But on the other hand JAVA, we use data types like int, float, double, etc which are not object-oriented, and of course which is opposite of OOP. So, why JAVA is not 100% objected oriented.
