🎨 Project 2 - Using Pandas in Streamlit

What are we building?

Let's now proceed to using Pandas in a Streamlit app. Particularly, we're going to create an app that allows the loading of a CSV data upon clicking on a button.

How the code works?

Here's an explanation of the code in a step-by-step manner:

1. Import necessary libraries
2. Display the title of the app
3. Create a conditional button that displays a Pandas DataFrame upon clicking on the Load data button

Code

import streamlit as st
import pandas as pd

st.title('🐼 Pandas - A minimum working example')

if st.button('Load data'):
  df = pd.read_csv('https://raw.githubusercontent.com/dataprofessor/data/master/delaney_solubility_with_descriptors.csv')
  st.write(df)
else:
  st.info('👆 Click on the button ')

Completed app

The above code gives us the following Streamlit app (GitHub repo | Demo app)

Homework

Now that you have this Pandas app completed, can you build upon this Streamlit app by adding input widgets for taking in user provided URL to a CSV file that can be used for displaying the CSV file as a DataFrame.
