Setup your Development Environment

Subject: Flask: Python Web Development

---

In our Python course we used the built-in IDLE development environment to write and run our Python programs, however as we continue to a more advanced (web) application development using Flask framework we will be needing more tools database connection and more task like coding HTML and CSS, then I will recommend we download a more powerful editor or IDE like VS Code.

We need to install the following for this course:

1. Visual Studio Code (VS Code): a powerful code editor with features include support for debugging, syntax highlighting, intelligent code completion, snippets, code refactoring, and embedded Git.
Visit: https://code.visualstudio.com/download to download and install VS Code on your computer.

2. Python extension for Visual Studio Code: In order to be able to run Python code easily in VS Code we need to install this extensions from VS Code. Installing extensions or needed tools is one of the advantages of VS Code.

3. Install Flask: also from VS Code, open a new terminal windows and use pip (pip is the package installer for Python) to install flask using this command:

pip install flask

(See attached images)

Now we are ready to program our web application using the Flask framework.

Note: the prerequisites for this course is that you must have gone through our HTML, CSS and Python courses.
