Advanced Functions. In this chapter, we go beyond the basics of using functions. I’ll assume you can define and work with functions taking default arguments: > def foo(a, b, x=3, y=2): ... return (a+b)/(x+y) ... > foo(5, 0) 1.0. > foo (10, 2, y=3) 2.0.
A function is a group of statements that exist within a program for the purpose of performing a specific task. Since the beginning of the semester we have been using a number of Python’s built-in functions, including: print() range() len() random.randint() ... etc.
