This course is taught in French Vous voulez comprendre l'arithmétique ? Vous souhaitez découvrir une application des mathématiques à la vie quotidienne ? Ce cours est fait pour vous ! De niveau première année d'université, vous apprendrez les bases de l'arithmétique (division euclidienne, théorème de Bézout, nombres premiers, congruence). Vous vous êtes déjà demandé comment sont sécurisées les transactions sur Internet ? Vous découvrirez les bases de la cryptographie, en commençant par les codes les plus simples pour aboutir au code RSA. Le code RSA est le code utilisé pour crypter les communications sur internet. Il est basé sur de l'arithmétique assez simple que l'on comprendra en détail. Vous pourrez en plus mettre en pratique vos connaissances par l'apprentissage de notions sur le langage de programmation Python. Vous travaillerez à l'aide de cours écrits et de vidéos, d'exercices corrigés en vidéos, des quiz, des travaux pratiques. Le cours est entièrement gratuit !
As a Python programmer, leveraging Flask allows you to quickly and easily build your own web applications. But before you share your apps on the Internet you should protect your users' data, ensuring information stored on your site is safe from unwanted manipulation. You could implement web security and permissions on your own, but relying on trusted providers is a faster, safer, and easier way to allow users to login to your application - without having to create and maintain another account, profile, and password. In this course, you will learn to implement the OAuth 2.0 framework to allow users to securely login to your web applications. You'll be provided a restaurant menu application created in Flask. By the end of this course, you will write the necessary code to implement Google+ Sign-In and Facebook Login in options so users can create restaurant menus that are viewable by everyone but only modifiable by the original creator.
In this course you'll learn the basic Linux fundamentals every web developer needs to know to share their web applications with the world! You'll get a basic Python WSGI application up and running within a Vagrant virtual machine that queries data from a PostgreSQL database. You'll start by exploring various Linux distributions and learning the differences between a number of them. You'll then explore how the Linux operating system differs from other operating systems you may be more familiar with. With this base knowledge, you'll then move into Linux security - covering topics such as file permissions, user management, package management and configuring firewalls. Finally, you'll transform a safe and secure baseline server into a web application server by installing and configuring the Apache HTTP Server and PostgreSQL database server.
In this free online course Diploma in Python Programming you will learn about the concepts of programming using the Python language. You will learn about creating variables and storing different types of data in them. You will learn about working with dates and time, making decisions with your code and using loops. You will learn about saving and reading files with your program. You will learn about creating functions and handling errors with your code.<br /><br />The course begins by introducing you to the concepts of programming. You will learn about creating your first Python program with Visual Studio. You will learn about commenting in your code and displaying text on screen. You will learn about how Python accepts multiple ways of containing a text string. You will learn about variables and the rules and guidelines for creating variables. You will learn about manipulating variables using built in functions, and briefly what functions are. You will learn about Visual Studio’s IntelliSense feature and its helpfulness when programming. <br /><br />Next, you will learn about storing numeric variables and their difference to string variables. You will learn about performing mathematical operations in your code. You will learn about formatting numbers and converting string variables to numeric variables. You will learn about working with date and time, displacing dates and getting today's date using functions. You will learn about formatting dates and importing libraries to help with the formatting. You will learn about working with time and how to reuse the same functions to format time as you did dates.<br /><br />Next, you will learn about how you code check conditions and make decisions with the if statement. You will learn about the constraints for checking an if statement and how there are generally two different ways to write every if statement. You will learn about using the elif statement for checking multiple conditions. You will learn about combining conditions using logic operations and nesting if statements.<br /><br />Next, you will learn about the concepts of loops, and using the turtle library to draw on screen. You will learn about creating and using for loops. You will also learn about creating and using while loops, and the differences between for and while loops. You will learn about common mistakes made when using loops. <br /><br />Next, you will learn about using and creating lists to store multiple values. You will learn about how to modify and delete from your list. You will learn about searching a list and sorting it. You will learn about creating and writing to files. You will learn about closing the file after your finished using it. You will learn about opening files and reading data from them. You will learn about csv files and what they are. <br /><br />Finally, you will learn about what functions are and how to create functions. You will learn about passing parameters in to your functions and why you should use functions. You will learn what types of errors can occur and how to handle errors. You will learn how to use the try/except statement to handle possible errors and get information on errors that occurred. You will learn how to save functions in a separate file and import them into your main program file as you need them.<br /><br />This free Alison course will be of great interest to those learners who wish to get started in programming and improve their ability to write programs using the Python programming language.
This course is intended for budding full-stack web developers to master the basics of HTTP, the protocol that underlies all web technology. In this course, you'll explore HTTP directly, talking with web servers and browsers by hand. You'll write and deploy low-level web applications in Python. And you'll learn more about how HTTP connects with other web technologies.
In this introduction to computer programming course, you’ll learn and practice key computer science concepts by building your own versions of popular web applications. You’ll learn Python, a powerful, easy-to-learn, and widely used programming language, and you’ll explore computer science basics, as you build your own search engine and social network.
This course will introduce you to the world of data analysis. You'll learn how to go through the entire data analysis process, which includes: * Posing a question * Wrangling your data into a format you can use and fixing any problems with it * Exploring the data, finding patterns in it, and building your intuition about it * Drawing conclusions and/or making predictions * Communicating your findings You'll also learn how to use the Python libraries NumPy, Pandas, and Matplotlib to write code that's cleaner, more concise, and runs faster. This course is part of the [Data Analyst Nanodegree](https://www.udacity.com/course/data-analyst-nanodegree--nd002).
