Exercises in Programming Style by Cristina Videira Lopes My rating: 5 of 5 stars An easily consumed, enjoyable read, and excellent review of the history of programming style, from older days of constrained memory and monolithic styles, through pipelining and object-oriented variants, to more recent patterns like model-view-controller (MVC), mapreduce, and representational state transfer (ReST). Along the way, each variant is described, along with its constraints, its history, and its context in systems design. View all my reviews

I am currently working through Computational Statistics in Python 's module Functions are first class objects , and for this - I have worked with delegates and higher order functions in other languages - I put together this example to better grasp higher order functions in Python: def power_function(num, power): """power of num.""" return num**power def add_function(num, more): """sum of num.""" return num+more def runFunction(fx, x, y): return fx(x,y) num = 2 powers = range(0,64) arrPower = list(map(lambda x: runFunction(power_function, num, x), powers)) arrAdd = list(map(lambda x: runFunction(add_function, num, x), powers)) arrPower arrAdd
