Python numpy.defchararray.decode()用法及代碼示例

numpy.core.defchararray.decode(arr，encoding)：此numpy函數根據指定的編解碼器解碼字符串(對象)。

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

返回: Decoded string

代碼:

# Python Program illustrating  
# numpy.char.decode() method  
import numpy as np  
  
arr1 = ['eAAAa', 'ttttds', 'AAtAAt'] 
arr2 = ['11sf', 'sdsf2', '1111f2'] 
  
print ("\narr1:", arr1) 
print ("\narr2:", arr2) 
  
# Using np.char.encode() 
encode_arr1 = np.char.encode(arr1, encoding ='cp037') 
print ("\nEncoded arr1:\n", encode_arr1) 
  
encode_arr2 = np.char.encode(arr2, encoding ='utf8') 
print ("\nEncoded arr2:\n", encode_arr2) 
  
# Using np.char.decode() 
decode_arr1 = np.char.decode(encode_arr1, encoding ='cp037') 
print ("\nDecoded arr1:\n", decode_arr1) 
  
decode_arr2 = np.char.decode(encode_arr2, encoding ='cp037') 
print ("\nDecoded arr1:\n", decode_arr2) 
  
decode_arr2 = np.char.decode(encode_arr2, encoding ='utf8') 
print ("\nDecoded arr1:\n", decode_arr2)

輸出：

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']

Decoded arr1:
 ['eAAAa' 'ttttds' 'AAtAAt']

Decoded arr2:
 ['\x91\x91ËÃ' 'ËÀËÃ\x16' '\x91\x91\x91\x91Ã\x16']

Decoded arr2:
 ['11sf' 'sdsf2' '1111f2']
