Both Java and Python are general-purpose languages. Java’s performance is faster than Python, but it takes much more code to achieve similar ends. Java is harder to learn but is very powerful for creating programs that run on multiple platforms.
static typing vs dynamic typing
A significant difference between Java and Python is that Java prefers that you define a variable’s type when first declared. After that, it will not let you change it — this is called static typing. On the other hand, Python takes an approach called dynamic typing. You can change a variable’s type, for example from string to integer or vice versa.
Another difference is that Java programs are platform independent — any mobile unit or standard computer that can run a Java Virtual Machine can launch a Java app. In contrast, Python programs must be compiled to convert your code into code that different operating systems can comprehend.
