Overview of this book

This book is a comprehensive guide to the Streamlit open-source Python library and simplifying the process of creating web applications. Through hands-on guidance and realistic examples, you’ll progress from crafting simple to sophisticated web applications from scratch. This book covers everything from understanding Streamlit's central principles, modules, basic features, and widgets to advanced skills such as dealing with databases, hashes, sessions, and multipages. Starting with fundamental concepts like operation systems virtualization, IDEs, development environments, widgets, scripting, and the anatomy of web apps, the initial chapters set the groundwork. You’ll then apply this knowledge to develop some real web apps, gradually advancing to more complex apps, incorporating features like natural language processing (NLP), computer vision, dashboards with interactive charts, file uploading, and much more. The book concludes by delving into the implementation of advanced skills and deployment techniques. By the end of this book, you’ll have transformed into a proficient developer, equipped with advanced skills for handling databases, implementing secure login processes, managing session states, creating multipage applications, and seamlessly deploying them on the cloud.

Exploring the multi-pages feature

Multi-pages in Streamlit are a way to organize your app into multiple pages, each with its own content. This can be useful for large apps with a lot of functionalities, or for apps that need to be divided into different sections for different users.

To create a multi-page app in Streamlit, you simply need to create a new folder called pages in the same folder as your main app file. Then, create new Python files inside the pages folder, each of which will represent a different page in your app.

Once you have created your pages, you can start adding content to them. You can use any Streamlit widgets and functions that you want, just like you would in a regular Streamlit app.

When you run your app, Streamlit will automatically detect the pages in the pages folder and add them to a navigation bar in the sidebar. Users can then click on the different pages to navigate between them.

According to the preceding explanation, everything sounds easy...
