numpy.core.defchararray.encode(arr, encoding): This numpy function encodes the string(object) based on the specified codec.

Parameters: arr : array-like or string. encoding : [str] Name of encoding being followed. error : Specifying how to handle error. Returns : Encoded string

Code: 

Python3




# Python Program illustrating
# numpy.char.encode() method
import numpy as np
 
arr1 = ['eAAAa', 'ttttds', 'AAtAAt']
arr2 = ['11sf', 'sdsf2', '1111f2']
 
# Printing the array
print ("\narr1 : ", arr1)
print ("\narr2 : ", arr2)
 
print ("\nEncoded arr1 : \n", np.char.encode(arr1, encoding ='cp037'))
print ("\nEncoded arr2 : \n", np.char.encode(arr2, encoding ='utf8'))
print ("\nEncoded arr2 : \n", np.char.encode(arr2, encoding ='utf8',
                                                 errors = 'strict'))

Output:

arr1 :  ['eAAAa', 'ttttds', 'AAtAAt']
arr2 :  ['11sf', 'sdsf2', '1111f2']

Encoded arr1 : 
 [b'\x85\xc1\xc1\xc1\x81' b'\xa3\xa3\xa3\xa3\x84\xa2'
 b'\xc1\xc1\xa3\xc1\xc1\xa3']

Encoded arr2 : 
 [b'11sf' b'sdsf2' b'1111f2']

Encoded arr2 : 
 [b'11sf' b'sdsf2' b'1111f2']
