python dump __repr__到stderr，带有干净的换行符

Question

想知道是否有办法将实例的__repr__转储到stderr而没有所有Apache的日志格式垃圾？

目前这是代码

    def __repr__(self):
        # instance's repr of the object
        str = "<MyObj(\n"

        for col in db_fields:
            str += "%s = %s \n" % (col, self.get_db_col(col))

        str += ")> \n"

        return str

    # main script
    sys.stderr.write("%r", my_obj)

日志输出目前是：

[Mon Feb 09 10:28:02 2015] [error] [client 1.1.1.1] <MyObj(, referer: https://some.domain.com/
[Mon Feb 09 10:28:02 2015] [error] [client 1.1.1.1] db_field_1 = 1 , referer: https://some.domain.com/
[Mon Feb 09 10:28:02 2015] [error] [client 1.1.1.1] db_field_2 = False , referer: https://some.domain.com/
[Mon Feb 09 10:28:02 2015] [error] [client 1.1.1.1] db_field_3 = 'Descr' , referer: https://some.domain.com/
[Mon Feb 09 10:28:02 2015] [error] [client 1.1.1.1] )>

不可能阅读它，有没有办法在不触及Apache的conf的情况下以某种方式欺骗它？

我希望得到的结果是：

[Mon Feb 09 10:28:02 2015] [error] [client 1.1.1.1] <MyObj(, referer: https://some.domain.com/
db_field_1 = 1 , referer: https://some.domain.com/
db_field_2 = False , referer: https://some.domain.com/
db_field_3 = 'Descr' , referer: https://some.domain.com/
