... ways the opposite of object-oriented programming: focus is on functions, all data is passive -- in OO the data name is first: x.f(), while in functional programming the function name is first: f(x). Functions can be used in F.P. like objects in OO: local functions are allowed, functions can be pas ...

... The'+' operator behaves differently with different data types. With integers it adds the two numbers and with strings it concatenates or joins two strings. For example: Print 8+9 will give 17 and Print "Python" + "programming" will give the output as Pythonprogramming. This feature where an operator ...

... A lambda expression has the form: (lambda argument-list function-body ) In other words, a lambda expression is somewhat like defun, except that it defines an unnamed function, or it allows the user to define a function with no name. For example, ((lambda (x y) (+ x y)) 2 3) binds x and y to 2 an ...
