We will need a command-line interface for communication with the system.
- [Instructor] Welcome back.…In the last video we saw how to install a text editor.…In this video we'll see how to use a command-line interface.…So the text editor is where we'll write the code.…The command-line is where we'll type commands…to and from the code.…For OS X and Linux there should already be…a command line program installed called Terminal.…So on a Mac you can just click on the Spotlight…and type in Terminal.…For Windows we'll need to install…a command line program called Cygwin.…
You can install it by going to cygwin.com/install.html.…So after opening up Terminal you'll see…a window that looks like this.…There are a few common commands…that we'll use over and over again…so let's take a look at them now.…Pwd prints the current working directory.…Ls lists the files in the current directory.…Ls -al lists all the files and folders…in the current directory.…
Cd navigates into a directory.…Cd ../ goes back up one level.…Mkdir makes a new directory.…And touch creates a new file.…So those are seven common commands.…
The need for talented developers is greater than ever before. A basic grounding in a framework as simple, powerful, and easy-to-learn as Flask—a Python micro framework—can help launch your programming career. Get a basic grounding in the fundamental concepts of web development, as well as the hands-on experience required to successfully build web apps with Flask, in this course with Packt trainer Lalith Polepeddi.
It starts with turning your computer into a modern development machine. Then learn everything you need to know about Flask: models, views, controllers, web templates, forms, validation, and API interactions. Lalith shows how to apply these concepts and develop a powerful database-backed Flask app, including a full authentication system. Finally, Lalith shows how to extend the app's functionality by integrating it with third-party APIs. When you finish this course, you will be fully equipped to build your very own custom web apps with Flash.
