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.

Using Streamlit Components – streamlit-lottie

As we talked about at the beginning of this chapter, lottie is a web-native, open source library created by Airbnb to make putting animations on your website just as easy as putting static images on it. It is very common for large, profitable tech companies to put out open source software as a way of giving back to the developer community (or, more likely, to recruit developers who think their software is cool), and this is no exception. In this case, streamlit-lottie wraps around lottie files and places them directly into our Streamlit apps. 

To do this, we first need to import the streamlit-lottie library, and then point the st_lottie() function to our lottie file. We can either import a local lottie file or, more likely, we can find a useful animation file on the free site ( and load it from there into our app. 

To test this out, we can add a cute penguin animation (https://lottiefiles...
