Subtracting a pandas DataFrame from another DataFrame

Overview:

Python pandas library provides multitude of functions to work on two dimensioanl Data through the DataFrame class.
The sub() method of pandas DataFrame subtracts the elements of one DataFrame from the elements of another DataFrame.
Invoking sub() method on a DataFrame object is equivalent to calling the binary subtraction operator(-).
The sub() method supports passing a parameter for missing values(np.nan, None).

import pandas as pd

# Create Data

data1 = [(2, 4, 6, 8),

(1, 3, 5, 7),

(5, 0, 0, 9)];

data2 = [(1, 1, 0 , 1),

(1, 0, 1 , 1),

(0, 1, 1 , 0)];

# Construct DataFrame1

dataFrame1 = pd.DataFrame(data=data1);

print("DataFrame1:");

print(dataFrame1);

# Construct DataFrame2

dataFrame2 = pd.DataFrame(data=data2);

print("DataFrame2:");

print(dataFrame2);

# Subtracting DataFrame2 from DataFrame1

subtractionResults = dataFrame1 - dataFrame2;

print("Result of subtracting dataFrame1 from dataFrame2:");

print(subtractionResults);

DataFrame1:

0 1 2 3

0 2 4 6 8

1 1 3 5 7

2 5 0 0 9

DataFrame2:

0 1 2 3

0 1 1 0 1

1 1 0 1 1

2 0 1 1 0

Result of subtracting dataFrame1 from dataFrame2:

0 1 2 3

0 1 3 6 7

1 0 3 4 6

2 5 -1 -1 9
