This article will teach you about a third-party library designed specifically for data scientists (machine learning engineers) based on Python —- Streamlit. With just a few lines of code, you can create visually appealing applications that are very convenient and practical. This article covers everything from installation and commonly used methods to finally implementing a simple demo, providing a complete guide on how to use this library. If you are interested in this method, feel free to leave a like and a message at the end of the article, and Cloud君 will demonstrate a complete machine learning practical project using Streamlit in the future.
