    df: Py<PyAny>,
    func: Py<PyAny>,
) -> PyResult<Py<PyAny>>

Apply a scirs2 function to each column of a DataFrame

Example (Python)

import pandas as pd
import scirs2

df = pd.DataFrame({
    'A': [1, 2, 3, 4, 5],
    'B': [2, 4, 6, 8, 10],
    'C': [1, 3, 5, 7, 9]
})

# Calculate mean of each column
means = scirs2.apply_to_dataframe(df, scirs2.mean_py)
