numpy.core.defchararray.greater(arr1, arr2) is another function for doing string operations in numpy. It checks the elements of two same shaped string array one by one and returns True if the elements of arr1 greater than the elements of arr2 i.e. arr1 > arr2 .Otherwise, it returns False.
 

Parameters: 
arr1 : array_like of str or unicode.1st input array. 
arr2 : array_like of str or unicode.2nd input array.
Returns : [ndarray] Output array of bools, or a single bool if arr1 and arr2 are scalars.

Code #1 : 
 

Python3




# Python program explaining
# numpy.char.greater() 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 in_arr1 > in_arr2
out_arr = geek.char.greater(in_arr1, in_arr2)
print ("Output array: ", out_arr)

Output: 

1st Input array :  numpy
2nd Input array :  nump
Output array:  True

 

  
Code #2 : 
 

Python3




# Python program explaining
# numpy.char.greater() method
 
# importing numpy
import numpy as geek
 
# input arrays 
in_arr1 = geek.array(['Geeks', 'for', 'Geek', 'numpy'])
print ("1st Input array : ", in_arr1)
 
in_arr2 = geek.array(['Geek', 'for', 'Geek', 'Numpy'])
print ("2nd Input array : ", in_arr2)
 
# checking if in_arr1 > in_arr2
out_arr = geek.char.greater(in_arr1, in_arr2)
print ("Output array: ", out_arr)

Output: 

1st Input array :  ['Geeks' 'for' 'Geek' 'numpy']
2nd Input array :  ['Geek' 'for' 'Geek' 'Numpy']
Output array:  [ True False False  True]

 

  
Code #3 : 
 

Python3




# Python program explaining
# numpy.char.greater() method
 
# importing numpy
import numpy as geek
 
# input arrays 
in_arr1 = geek.array(['10', '11', '122', '15'])
print ("1st Input array : ", in_arr1)
 
in_arr2 = geek.array(['10', '13', '121', '14'])
print ("2nd Input array : ", in_arr2)
 
 
# checking if in_arr1 > in_arr2
out_arr = geek.char.greater(in_arr1, in_arr2)
print ("Output array: ", out_arr)

Output: 

1st Input array :  ['10' '11' '122' '15']
2nd Input array :  ['10' '13' '121' '14']
Output array:  [False False  True  True]
