Streamlit Hello World

Streamlit App

In this course, we'll learn to develop web apps using the Streamlit library. With just a few lines of code, we can have our app up and running in no time.

We'll start off with learning about the various components of Streamlit. We then finally build an app that we can deploy and which our users can access.

Develop Web Apps with Streamlit

# Improve application efficiency
Streamlit provides a way to make our applications more efficient with the `@st.cache` decorator. This enables our application to use stored values in any computation required. The application doesn’t need to fetch data afresh each time the computation runs unless one of three following things happens:
 
- A function’s input parameters change.
- A function’s body changes.
- An inner function changes.

To use it, we call the decorator just before defining the function. The code below demonstrates the benefits of using the `@st.cache` decorator:

# Execute the example
Let’s run the application below to see the benefit of using `@st.cache` to improve efficiency:
