9. (Monty) Python very high-level programming language highly modular
object-oriented
automatic memory management
dynamic typing
interactive
very easy to learn

10. Hello World – Program In Java: In Python: class HelloWorld {
public static void main(String[] args) {
System.out.println(”Hello World!”); }
In Python:
print ”Hello World!”
