# Streamlit Overview ## Streamlit: The Basics [Streamlit](https://www.streamlit.io/) is an open-source Python library that makes it easy to create and share beautiful, custom web apps for machine learning and data science. In just a few minutes you can build and deploy powerful data apps. In practice, a Streamlit application is just a `.py` file where you add a few Streamlit commands and then you run it with `streamlit run`: ``` streamlit run your_script.py [-- script args] ``` As soon as you run the script as shown above, a local Streamlit server will spin up and your app will open in a new tab in your default web browser. This app is your canvas, where you'll draw charts, text, widgets, tables, and more. This `.py` file is all you need to build a fully-featured web-app! What gets drawn in the app is up to you. For example [`st.text`](https://docs.streamlit.io/library/api-reference/text/st.text) writes raw text to your Streamlit app, and [`st.line_chart`](https://docs.streamlit.io/library/api-reference/charts/st.line_chart) draws a line chart. Refer to Streamlit's [API documentation](https://docs.streamlit.io/library/api-reference) to see all commands that are available to you. ## Core Concepts in Streamlit New to writing Streamlit applications and looking to understand more?
