Python Eval强制将字符串转换成dict类型出错，evaldict,我有个字符串如下：{\"

我有个字符串如下：{\"module\":\"sink\", \"hostname\":\"datastream2\", \"tag\":\"urs_queryuser_mq\", \"category\":\"mq\", \"ruler\":\"MQ_55f85a369b22441e\", \"count\":425, \"totalDelay\":-1, \"totalProcessDelay\":2947890, \"time\":1430395550006}"

当我使用Python shell 时 ：

ddb='{\"module\":\"sink\", \"hostname\":\"datastream2\", \"tag\":\"urs_yd_login\", \"category\":\"hdfs\", \"ruler\":\"HDFS_5aedbdf799494932\", \"count\":2, \"totalDelay\":-1, \"totalProcessDelay\":24115, \"time\":1430360048929}'
eval(ddb)
{'category': 'hdfs', 'count': 2, 'tag': 'urs_yd_login', 'totalDelay': -1, 'time': 1430360048929, 'totalProcessDelay': 24115, 'ruler': 'HDFS_5aedbdf799494932', 'hostname': 'datastream2', 'module': 'sink'}

此时能够正常转换成字典类型，但是在程序里边这样写就会抛出异常：

脚本如下格式：
print format_data[1]
ddddd = r'%s' % format_data[1].strip('"')
print ddddd

log_detail = eval(ddddd)

输出如下:
{\"module\":\"sink\", \"hostname\":\"datastream2\", \"tag\":\"urs_queryuser_mq\", \"category\":\"mq\", \"ruler\":\"MQ_55f85a369b22441e\", \"count\":425, \"totalDelay\":-1, \"totalProcessDelay\":2947890, \"time\":1430395550006}"
{\"module\":\"sink\", \"hostname\":\"datastream2\", \"tag\":\"urs_queryuser_mq\", \"category\":\"mq\", \"ruler\":\"MQ_55f85a369b22441e\", \"count\":425, \"totalDelay\":-1, \"totalProcessDelay\":2947890, \"time\":1430395550006}
unexpected character after line continuation character (, line 1)

麻烦各位大侠，帮小弟指点指点。

import jsonjson_str = {\"module\":\"sink\", \"hostname\":\"datastream2\", \"tag\":\"urs_queryuser_mq\", \"category\":\"mq\", \"ruler\":\"MQ_55f85a369b22441e\", \"count\":425, \"totalDelay\":-1, \"totalProcessDelay\":2947890, \"time\":1430395550006}my_dic = json.loads(json_str)
