哎哎哎:# t0]https://www . geeksforgeeks . org/num py-defchararray-decode-in-python/
numpy.core.defchararray.decode(arr, encoding) : 这个 numpy 函数根据指定的编解码器解码字符串(对象)。
参数: arr : 阵状或弦状。 编码:【str】正在遵循的编解码器名称。 错误:指定如何处理错误。
返回:解码字符串
代码:
# 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)
输出:
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']
