EncodeError 与 \xa3（井号）

Question

我正在尝试从网页中获取一些数据。该网页已声明字符集为utf-8。但是 \xa3 符号有问题。我无法编码或解码into/from 'utf-8'.

for key,value in self.__dict__.iteritems():
            if key not in self.db_attributes:
                print repr(value)
                attrs_statement+=str(key)+', '
                values_statement+=str(value)+', '

错误：

u'\xa3410'
Traceback (most recent call last):
  File "C:\Users\Milano\My Documents\LiClipse Workspace\Velvet_scraper\vehicle.py", line 432, in <module>
    v.prepare_insert_statement('motorhog_temp')
  File "C:\Users\Milano\My Documents\LiClipse Workspace\Velvet_scraper\vehicle.py", line 381, in prepare_insert_statement
    values_statement+=str(value)+', '
UnicodeEncodeError: 'ascii' codec can't encode character u'\xa3' in position 0: ordinal not in range(128)

请问有什么问题吗？

编辑：

整个方法：

def prepare_insert_statement(self,table):
        log('prepare_insert_statement, table: {0}'.format(table))

        attrs_statement = "("
        values_statement = "("

        for key,value in self.__dict__.iteritems():
            if key not in self.db_attributes:
                print repr(value)
                attrs_statement+=key+', '
                values_statement+=value+', '

        attrs_statement+=')'
        values_statement+=')'
        statement = """INSERT INTO TABLE {0}{1} VALUES{2}""".format(table,attrs_statement,values_statement)
        return statement

str() 使用 ASCII 编解码器隐式编码 Unicode 对象。显式编码您的对象，或者不使用 str() 对象并构建一个 Unicode 字符串：

values_statement += value.encode('utf8') + ', '
