eq() Function Of Pandas DataFrame Class

Overview:

The eq() method of DataFrame class implements the binary operation "Logical Equal To" also called as the "Equality" operation.
The eq() method when invoked on a DataFrame instance, checks each element of the instance with the element of another DataFrame instance for equality.
The results of the equality tests are returned in a separate DataFrame instance whose elements are Boolean values. A value True indicates the corresponding DataFrame elements were equal in the value. A value False indicates the elements were unequal.

import pandas as pd

# Floating point data

floats1 = [(1.1, 1.2, 1.3),

(0.1, 0.2, 0.3),

(2.1, 2.2, 2.3)];

floats2 = [(0.50, 2.50, 1.0),

(0.1, 0.2, 0.4),

(1.5, 2.5, 3.35)];

# Floating point data into DataFrames

dataFrame1 = pd.DataFrame(data=floats1);

dataFrame2 = pd.DataFrame(data=floats2);

equalityResults = dataFrame1.eq(dataFrame2);

# Print the pandas DataFrames and the result of Equality Test

print("Contents of DataFrame1:");

print(dataFrame1);

print("Contents of DataFrame2:");

print(dataFrame2);

print("DataFrame1.eq(DataFrame2):");

print(equalityResults);

Contents of DataFrame1:

0 1 2

0 1.1 1.2 1.3

1 0.1 0.2 0.3

2 2.1 2.2 2.3

Contents of DataFrame2:

0 1 2

0 0.5 2.5 1.00

1 0.1 0.2 0.40

2 1.5 2.5 3.35

DataFrame1.eq(DataFrame2):

0 1 2

0 False False False

1 True True False

2 False False False
