numpy.core.defchararray.less_equal (arr1, arr2) — this is another function for doing string operations in numpy. It checks the elements of two identical string arrays one at a time and returns True if the arr1 elements are less than or equal to the arr2 elements i.e. arr1 & lt; = 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.less_equal () method

# numpy imports

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 & lt; = in_arr2

out_arr = geek.char.less_equal (in_arr1, in_arr2)

print ( "Output array:" , out_arr)

Exit:

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

Code # 2:

# Python program explaining
# numpy.char.less_equal () 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 & lt; = in_arr2

out_arr = geek.char.less_equal (in_arr1, in_ar r2)

print ( "Output array : " , out_arr)

Output:

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

Code # 3:

# Python program explaining
# numpy.char.less_equal () 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’ , ’ 141’ ])

print ( "2nd Input array: " , in_arr2)

# check if in_arr1 & lt; = in_arr2

out_arr = geek.char.less_equal (in_arr1, in_arr2)

print ( "Output array:" , out_arr)

Output:

 1st Input array: [’10’’ 11’ ’122’’ 15’] 2nd Input array: [’10’’ 13’ ’121’’ 141’] Output array: [True True False False ]

Maybe there are another answers? What operations with empty strings | less_equal () function exactly means?. I just hope that will not emerge anymore

Simply put and clear. Thank you for sharing. operations with empty strings | less_equal () function and other issues with exp was always my weak point 😁. Will use it in my bachelor thesis
