Lecture Zero-Argument Functions Yes, functions can take 0 arguments. Functions always re-evaluate their bodies when called. Dice Functions In the Hog project, dice are functions that are...

Lambda Function Environments A lambda function’s parent is the frame where the lambda expression is evaluated (where lambda appears). a = 1 def f(g): a = 2 return lambda y: a * g(y) # ...

Function Currying We manipulate functions such that instead of posessing multiple arguments, they become a higher order function that accepts a single argument and returns other functions to pro...

Lambda Expressions Expressions that evaluate to a function. We can directly assign a name to a function without defining it in our frame with def x = 10 square = x * x ...

Higher Order Functions are enabled by Environments Higher-order Function: A function that takes a function as an argument or returns a function as a return value. def apply_twice(f, x): return...

Designing Functions A function’s domain is the set of all inputs it might possibly take as arguments. A function’s range is the set of output values it might possibly return ...

Control Print and None Pure functions just returns a value. None-pure functions have a side effect. Print is a none-pure function that always returns None, but also displays a given value. ...

Control Print and None Pure functions just returns a value. None-pure functions have a side effect. Print is a none-pure function that always returns None, but also displays a given value. ...

Higher-Order Functions Allow to design functions with very general methods of computation A function that takes another function as an argument Generalizing Patterns with Arguments For ce...
