python提示UnicodeDecodeError: ‘utf8’ codec can’t decode byte 0xa1 in position 6: invalid start byte

用json解析字符串发现编码错误

records=[json.loads(line) for line in open(path)]

错误提示

UnicodeDecodeError: ‘utf8’ codec can’t decode byte 0xa1 in position 6: invalid start byte

解决办法：解析字符串的语句改为

records=[json.loads(unicode(line,'ISO-8859-1')) for line in open(path)]

将：

j = json.loads(line.decode('utf-8'))             

改为：

 j = json.loads(line.decode('ISO-8859-1'))
