Introduction

In this blog post, we will learn how to build a simple Streamlit app. We will cover the following topics:

  • Creating a new Streamlit project
  • Adding widgets to your app
  • Displaying data in your app
  • Running your Streamlit app

Creating a new Streamlit project

To create a new Streamlit project, you will need to install the Streamlit library. You can do this by running the following command in your terminal:

pip install streamlit

Once you have installed Streamlit, you can create a new Python file and import the Streamlit library.

Python
import streamlit as st

Adding widgets to your app

Widgets are interactive elements that allow users to interact with your app. There are many different types of widgets available, such as text boxes, sliders, and buttons.

To add a widget to your app, you can use the st. function. For example, to add a text box, you would use the following code:

Python
st.text_input("Enter your name:")

Displaying data in your app

You can display data in your app using the st. function. For example, to display a list of numbers, you would use the following code:

Python
numbers = [1, 2, 3, 4, 5]

st.write(numbers)

Running your Streamlit app

To run your Streamlit app, you can use the following command in your terminal:

streamlit run my_app.py

This will start a local web server and open your app in your browser.

Here is an example of a simple Streamlit app that displays a text box and a button:

Python
import streamlit as st

st.text_input("Enter your name:")

st.button("Submit")

st_input_submit

This app will display a text box and a button. When the user clicks the button, the text that they entered in the text box will be printed to the console.

I hope this helps!
