Overview

The char.less() function in Python is used to check, one by one, if the elements of the array x1 are less than the elements of another array x2 that is of the same shape. This function returns True if x1 is less than x2. Otherwise, it returns False.

Syntax

char.less(x1, x2)

Parameter value

The char.less() function takes two parameter values, x1 and x2, which are two input arrays of the same shape.

Return value

The char.less() function returns an output array of bools.

Code example

import numpy as np
# creating input arrays
myarray1 = np.array(['1', '10', '122'])
myarray2 = np.array(['1', '13', '121'])
# printing the arrays
print(myarray1)
print(myarray2)
# implementing the char.less() function on both arrays
print(np.char.less(myarray1, myarray2))
Implementing the "char.less()" function

Code explanation

  • Line 1: We import the numpy module.
  • Lines 4–5: We create the input arrays, myarray1 and myarray2, using the array() function.
  • Lines 8–9: We print the arrays myarray1 and myarray2.
  • Line 12: We implement the char.less() function on both the arrays to check if the elements in myarray1 are less than the elements in myarray2. And then, we print the result to the console.
