Ploomber AI Editor | csv-viewer-1da7

App Description

Create a Streamlit application that has a text field to enter a URL (default value: https://raw.githubusercontent.com/mwaskom/seaborn-data/master/penguins.csv). The app should read the CSV file (and cache it) from the URL and display a DataFrame. Add controls to do the following: - Control how many rows are displayed - A checkbox to determine to randomly shuffle the DataFrame

To upload files, please first save the app

Code Editor for app.py

import streamlit as st
import pandas as pd

# Default URL
url = st.text_input('Enter CSV URL', 'https://raw.githubusercontent.com/mwaskom/seaborn-data/master/penguins.csv')

# Read CSV and cache it
@st.cache_data
def load_data(url):
    return pd.read_csv(url)

# Load data
try:
    df = load_data(url)
except Exception as e:
    st.error(f'Error loading data: {e}')
    df = pd.DataFrame()  # create an empty DataFrame in case of error

# Controls for displaying data
num_rows = st.slider('Select number of rows to display', min_value=1, max_value=len(df), value=5)
shuffle = st.checkbox('Shuffle DataFrame')

# Shuffle if checked
if shuffle:
    df = df.sample(frac=1).reset_index(drop=True)

# Display DataFrame
st.write(df.head(num_rows))
