Dataframe Division Operations

Overview:

  • div() method divides element-wise division of one pandas DataFrame by another.
  • DataFrame elements can be divided by a pandas series or by a Python sequence as well.
  • Calling div() on a DataFrame instance is equivalent to invoking the division operator (/).
  • The div() method provides the fill_value parameter which is used for replacing the np.nan and None values present in the DataFrame or in the resultant value with any other value.

Example:

import pandas as pd

 

# Data creation part

data1 = [(20, 40, 60, 80),

         (10, 30, 50, 70),

         (15, 25, 35, 45)];

 

data2 = [(2, 3, 4, 6),

         (5, 1, 0, 3),

         (3, 6, 9, 1)];

 

# Creation of pandas DataFrames

dataFrame1 = pd.DataFrame(data=data1);

dataFrame2 = pd.DataFrame(data=data2);

 

# Divide the DataFrame1 elements by the elements of DataFrame2

divisionResults = dataFrame1.div(dataFrame2);

 

print("Elements of DataFrame1:")

print(dataFrame1);

 

print("Elements of DataFrame2:")

print(dataFrame2);

 

print("DataFrame1 elements divided by DataFrame2 elements:")

print(divisionResults);

 

Output:

Output of a python example program that divides one DataFrame by another DataFrame
