Python  

Getting Started

Python is a great object-oriented, interpreted, and interactive programming language. It is often compared (favorably of course  ) to Lisp, Tcl, Perl, Ruby, C#, Visual Basic, Visual Fox Pro, Scheme or Java... and it's much more fun.

Java Python
statically typed dynamically typed
In Java, all variable names
(along with their types) must be explicitly declared.

Attempting to assign an object of the wrong type to a variable name triggers a type exception.

That’s what it means to say that Java is a statically typed language. 		In Python, you never declare anything.

An assignment statement binds a name to an object, and the object can be of any type.

If a name is assigned to an object of one type, it may later be assigned to an object of a different type.

That’s what it means to say that Python is a dynamically typed language.
