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. |
