Getting Started with Streamlit for Data Science

By: Tyler Richards

Overview of this book

Streamlit shortens the development time for the creation of data-focused web applications, allowing data scientists to create web app prototypes using Python in hours instead of days. Getting Started with Streamlit for Data Science takes a hands-on approach to helping you learn the tips and tricks that will have you up and running with Streamlit in no time. You'll start with the fundamentals of Streamlit by creating a basic app and gradually build on the foundation by producing high-quality graphics with data visualization and testing machine learning models. As you advance through the chapters, you’ll walk through practical examples of both personal data projects and work-related data-focused web applications, and get to grips with more challenging topics such as using Streamlit Components, beautifying your apps, and quick deployment of your new apps. By the end of this book, you’ll be able to create dynamic web apps in Streamlit quickly and effortlessly using the power of Python.

Utilizing Streamlit themes

So far, our applications have all had the exact same background and color scheme, apart from the previous section on the color picker. Streamlit allows us to update our applications and change the color of the background and the various components in our app as a customization feature. Using this, we can create Streamlit apps that default to dark mode, or that have the perfect colors for our app, or even create themes that ensure that people affected by color-blindness can see all of our visualizations. 

There are two ways to edit the theme of an app – through the UI or through the same config.toml setup we used in Chapter 3, Data Visualization. When we run our Streamlit apps, in the top-right corner, there is a little hamburger icon. When we click that icon and then click Settings, we will see the following options pop up in the middle of our screen:
