But if you decide to expand the project at some point, you can also use this folder to store images or JavaScript files. Just like above, you use url_for(), and Flask creates the full URL to the given view for you.So, even when you decide to change the route to one of your pages, the navigation menu will still work. When you use url_for(), Flask creates the full URL to the given view for you.

On the other hand, Plotly and Seaborn can help make your data more understandable and engaging when creating visualizations. For more computationally demanding tasks, libraries like LightGBM and XGBoost offer efficient implementations of gradient-boosting algorithms that handle large datasets with high dimensionality. One of the key features of NumPy is its implementation in C, which allows for rapid execution of complex mathematical computations using vectorized operations. This results in a notable performance improvement compared to using Python’s native data structures and loops for similar tasks.

Selenium has four major components Selenium IDE, Selenium RC, Selenium Web driver, and Selenium GRID. Next, set a breakpoint on line 2 of hello.py by placing the cursor on the print call and pressing F9. Alternately, Advanced Python Web Dev Using Flask Lessons click in the editor’s left gutter, next to the line numbers. Data visualization in Python has advanced significantly, offering a wide array of techniques for showcasing data in meaningful and engaging ways.

  • Flask is based on WSGI(Web Server Gateway Interface) toolkit and Jinja2 template engine.
  • To demonstrate how to handle errors, you will create a route that greets a user from a list of usernames.
  • In the upcoming sections, you’ll add a navigation menu and style your web application.

Your current project structure is great for starting a Flask project. In this section, you’ll prepare the development environment for your Flask project. First, you’ll create a virtual environment and install all the dependencies that you need for your project.

What exactly is Flask? (Coming Soon)

Enhancing performance through multiprocessing in Python involves using the ‘multiprocessing’ module to run tasks in parallel across multiple CPU cores instead of sequentially on a single core. Get your team access to 9000+ top Tutorials Point courses anytime, anywhere. The deployment is not an easy topic to be digested by a beginner, and I prefer to provide a sample 100% configured and hide the real complexity covered by some nice scripts. To explain the deployment options, we need a full article that presents the possible and recommended architectures. This is not so user-friendly deployment method, but the app that we’ve mentioned as a sample comes with the necessary scripts to deploy the app instantly using Docker. Get structured support to learn faster, and make sure you’re doing it right.
