required to explain our ability to return functions in this way. Currying : We can use higher -order functions to convert a function that takes multiple arguments into a chain of functions that each take a single argument. More specifically, given a function f(x, y), we can define a function g such that g(x)(y) is equivalent to f(x, y).

ICS3U: Creating Simple Functions From the beginning, we have used several of the various functions that Python has to offer, such as print, input or range. We have also learned how to import additional functions, such as those in the math and random modules, for use in our programs. But we are not limited to the functions defined in

Functions and Return Values Functions can return a value or not. A function that doesn’t return a value is sometimes called a procedure. Actually, every function returns a value, but some return the special value None. A function that doesn’t return a value may still do useful work, for example, by printing a table of values.

Types of functions Sometimes functions do things • Like “Move Code” • May produce output with print • May change variables Sometimes functions produce values • Similar to mathematical functions • Many might say a function “returns a value” • Downey calls these functions “fruitful” functions (we’ll use this, but don’t expect people to generally be aware of

Functions in Python Most programming languages provide ways of defining the computational equivalent of this. For example, the math module contains the definition of a function called sqrt. This is a piece of Python code that, when given the value of an argument, computes and returns the square root of that argument. This allows us to write code such as:

PYTHON "To describe something as clever is NOT considered a compliment in the Python culture." – Alex Martelli, Python Cookbook. History: Python was invented by Guido van Rossum in the late 1980s. It was named after Monty Python‟s Flying Circus. Its main influence was ABC, a learning language he was part of designing in the 80s.
