numpy.core.defchararray.equal(arr1, arr2) is another function for doing string operations in numpy. It checks the elements of two same-shaped array one by one and returns True if they are equal. Otherwise, it returns False.
Parameters: arr1 : array_like of str or unicode. arr2 : array_like of str or unicode. Returns : [ndarray] Output array of bools, or a single bool if arr1 and arr2 are scalars.Code #1 :
# Python program explaining
# numpy.char.equal() method
# importing numpy
import numpy as geek
# input arrays
in_arr1 = geek.array('numpy')
print ("1st Input array : ", in_arr1)
in_arr2 = geek.array('numpy')
print ("2nd Input array : ", in_arr2)
# checking if they are equal
out_arr = geek.char.equal(in_arr1, in_arr2)
print ("Output array: ", out_arr)
Output:
Code #2 :
1st Input array : numpy 2nd Input array : numpy Output array: True
# Python program explaining
# numpy.char.equal() method
# importing numpy
import numpy as geek
# input arrays
in_arr1 = geek.array(['Geeks', 'for', 'Geeks'])
print ("1st Input array : ", in_arr1)
in_arr2 = geek.array(['Geek', 'for', 'Geek'])
print ("2nd Input array : ", in_arr2)
# checking if they are equal
out_arr = geek.char.equal(in_arr1, in_arr2)
print ("Output array: ", out_arr)
Output:
Code #3 :
1st Input array : ['Geeks' 'for' 'Geeks'] 2nd Input array : ['Geek' 'for' 'Geek'] Output array: [False True False]
# Python program explaining
# numpy.char.equal() method
# importing numpy
import numpy as geek
# input arrays
in_arr1 = geek.array(['10', '11', '12'])
print ("1st Input array : ", in_arr1)
in_arr2 = geek.array(['10', '11', '121'])
print ("2nd Input array : ", in_arr2)
# checking if they are equal
out_arr = geek.char.equal(in_arr1, in_arr2)
print ("Output array: ", out_arr)
Output:
1st Input array : ['10' '11' '12'] 2nd Input array : ['10' '11' '121'] Output array: [ True True False]
