operations with empty strings | more () function

numpy.core.defchararray.greater (arr1, arr2) — this is another function for doing string operations in numpy. It checks the elements of two identical string arrays one after the other and returns True if the arr1 elements are larger than the arr2 elements i.e.  arr1" arr2 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:

# Python program explaining # numpy.char.greater () method   # numpy import import numpy as geek   # input arrays in_arr1 = geek.array ( ’numpy’ ) print ( "1st Input array:" , in_arr1)   in_arr2 = geek.array ( ’nump’ ) print ( "2nd Input array : " , in_arr2)     # check 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:

# Python program explaining # numpy.char.greater () method   # numpy import 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)     # check 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:

# Python program explaining # numpy.char.greater () method   # numpy import 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)      # check 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]
