       Let’s go!
       Everyone uses a computer, but it’s another thing to drive it! Here you will learn the basics of programming.
       The objective of this book is twofold: to deepen mathematics through computer science and to master
       programming with the help of mathematics.
       Python
       Choosing a programming language to start with is tricky. You need a language with easy handling, well
       documented,withalargecommunityofusers.Pythonhasallthesequalitiesandmore.Itismodern,powerful
       and widely used, including by professional programmers.
       Despite all these qualities, starting programming (with Python or another language) is difficult. The best
       thing is to already have experience with the code, using Scratch for example. There are still big steps to
       climb and this book is here to accompany you.
       Objective
       Mastering Python will allow you to easily learn other languages. Especially since the language is not the
       most important, the most important things are the algorithms. Algorithms are like cooking recipes, you
       have to follow the instructions step by step and what counts is the final result and not the language with
       which the recipe was written. This book is therefore neither a complete Python manual nor a computer
       course, nor is it about using Python as a super-calculator.
       The aim is to discover algorithms, to learn step-by-step programming through mathematical/computer
       activities. This will allow you to put mathematics into practice with the willingness to limit yourself to the
       knowledge acquired during the first years.
       Mathematics for computer science
       Computer science for mathematics
       Since computers only handle numbers, mathematics is essential to communicate with them. Another
       example is the graphical on-screen display that requires a good understanding of the coordinates (x, y),
       trigonometry....
       Computers are a perfect match for mathematics! The computer becomes essential to manipulate very large
       numbers or to test conjecture on many cases. In this book you will discover fractals, L-systems, brownian
       trees and the beauty of complex mathematical phenomena.
