Overview

The char.compare_chararrays() function in Python performs the element-wise comparison of string data type arrays using the comparison operators.

Syntax

char.compare_chararrays(a1, a2, cmp, rstrip)
Syntax of the char.compare_chararrayas() function

Parameter value

The char.compare_chararrays() function takes the following parameter values:

  • a1 and a2: These represent the arrays to be compared.
  • cmp: This represents the type of comparison we want to do on the given arrays. The following are the valid operators we can use: <, <=, ==, >=, >, and !=.
  • rstrip: This takes a Boolean value, True or False, indicating whether spaces at the end of strings are removed before the comparison or not. If True, the spaces at the end of strings are removed before the comparison.

Return value

The char.compare_chararrays() function returns an array of type Boolean with the same size as the two input arrays passed to it.

Example

import numpy as np
# Creating the input arrays
a = np.array(["a", "b", "cde"])
b = np.array(["a", "a", "dec"])
# Printing the arrays
print(a)
print(b)
# Comparing the elements of the arrays element-wise to see if they are equal
print(np.char.compare_chararrays(a, b, '==', True))
