As a result, Python program design can be unconstrained and straightforward. At the same time Python is a 100 percent object-oriented language. How’s that? Well, simply put, everything in Python is an object. Functions are objects, first class objects (whatever that means). This fact ...
5.3 Case Study: Guessing Numbers This case study generates a random number and lets the user repeatedly guess a number until it is correct. The problem is to guess what number a computer has in mind. You will write a program that randomly generates an integer between 0 and 100, ...
Etudes for Programmers I got the idea for the"etudes"part of the name from this1978 bookbyCharles Wetherellthat was very influential to me when I was first learning to program. I still have my copy.
