IBM Sample Data — ~7k rows, 21 columns.
*bleep* Load the dataset in the browser terminal:
from pyodide.http import open_url
import pandas as pd
df = pd.read_csv(open_url("/datasets/WA_Fn-UseC_-Telco-Customer-Churn.csv"))
print(df.shape)
print(df.columns.tolist()) Running locally? The file inside the Kaggle download is already named WA_Fn-UseC_-Telco-Customer-Churn.csv — drop it into the notebook's working directory and the code above runs unchanged (swap open_url(...) for "WA_Fn-UseC_-Telco-Customer-Churn.csv").
