19 wrz 2024 · # Calculate the sum of each column: column_sums = df. sum () # Calculate the mean of each row: row_means = df.mean(axis= 1) # Explicitly specify axis for row-wise calculations Using Lambda Functions with .apply() You can create custom functions and apply them to rows or columns using .apply(). This offers flexibility for complex operations.
