Mastering Python for Data Science: Beyond the Basics

We’ve added 500+ learning opportunities to create one of the world’s most comprehensive free-to-degree online learning platforms. Selenium WebDriver supports various programming languages such as Java, C#, Python, Ruby, and more, allowing testers to write automated tests in their preferred language. Tip Debugging information can also be seen by hovering over code, such as variables.

  • This course covers connecting web or mobile applications to databases, implementing authentication, logging, caching, and more.
  • For instance, tasks like matrix multiplication, which are common in many scientific computations, can be executed swiftly using functions like np.dot().
  • Selenium is a widely used tool for testing Web-Based Applications that checks if they are doing as expected.
  • Selenium WebDriver is a robust open-source framework for automating web browsers, primarily aimed at easing the testing and verification of web applications.
  • Select the interpreter you installed at the beginning of the tutorial.
  • This ensures that the URLs formed are unique and based on precedents laid down by Apache.

If the main purpose of your Flask project were to just display plain strings, then you’d be done.However, it’s more fun to actually display dynamic content to your users. With the commands shown above, you create and activate a virtual environment named venv by using Python’s built-in venv module. The parenthesized (venv) in front of the prompt indicates that you’ve successfully activated the virtual environment.

You then use it to create your Flask application instance, giving it the name app. You pass the special variable __name__, which holds the name of the current Python module. This name tells the instance where it’s located; you need this because Flask sets up some paths behind the scenes. Jinja also supports template inheritance, allowing the creation of a base template that you can extend in child templates, promoting code reuse and a consistent layout across different pages of your project. With an application factory, your project’s structure becomes more organized. It encourages you to separate different parts of your application, like routes, configurations, and initializations, into different files later on.

What is Flask?

A practical and hands-on introduction to web development using Python and the Flask framework. Follow along with this course to build and deploy your own website to the cloud using online resources. To demonstrate how to handle errors, you will create a route that greets a user from a list of usernames. You use the escape() function you imported earlier to render the word string as text. If the user submits malicious JavaScript instead of a word, escape() will it render as text and the browser will not run it, keeping your web application safe.
