python编程中，有时会遇到以下错误，在此记录一下。

错误信息

ValueError: invalid literal for int() with base 10: ”

具体报错信息如下：

[2017-02-13 14:33:44,225] [ERROR] Internal Server Error: /data/notification/ Traceback (most recent call last): File “/data/python-virtualenv/cmdb-api/lib/python2.6/site-packages/django/core/handlers/base.py”, line 112, in get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) …… File “/data/python-virtualenv/cmdb-api/lib/python2.6/site-packages/django/db/models/fields/init.py”, line 613, in get_PRep_value return int(value) ValueError: invalid literal for int() with base 10: ”

原因：

不要被一大堆信息吓蒙掉，从报错信息上看这是一个类型转换错误： ‘’无法转为int型。

命令行下做测试
