我需要将'767f440128e1a00a'十六进制数据转换为打包的EBCDIC字符串。我希望将所有result
结果合并为一个字符串,但是python给出了Unicode错误UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe1 in position 0: unexpected end of data
s='767f440128e1a00a'
output = []
DDF = [1]
distance = 0
for y in range (1,len(s[2:])):
for x in DDF:
if s[2:][distance:x*2+distance]!='':
output.append(s[2:][distance:x*2+distance])
else:
continue
distance += x*2
print(output)
final=[]
result=''
bytearrya=[]
for x in output:
result=(str(bytearray.fromhex(x).decode()))
x = codecs.decode(x, "hex")
final.append(x)
[当您想解码此部分时会发生这种情况:\xe1
但在UTF-8中该字节不应与之相伴,应该跟随两个字节检查此表:
UTF-8 encoding table and Unicode characters
是说unexpected end of data
,因为该字节后面应有上表中的两个字节。我不确定您要在这里做什么,但这就是为什么您遇到此错误的原因。
您可以像这样稍微更改代码,以查看所使用的字节序列:
# after printing the output try this:
print(output)
# convert output list to bytearray to decode it later
utf8_literal = bytearray()
for x in output:
utf8_literal += bytearray.fromhex(x)
print(utf8_literal) # bytearray(b'\x7fD\x01(\xe1\xa0\n')
# try to decode it to utf-8
codecs.decode(utf8_literal) # 'utf-8' codec can't decode bytes in position 4-5: invalid continuation byte
消息有些不同,但仍然说相同的事情,即字节序列不正确,我不知道您是要测试随机数还是要从其他地方获取它们,但是您无法将其转换为[C0 ]如果不是有效的utf-8
字节序列。
