logging format 如何优雅地对齐

[2018-11-02 09:56:14] [INFO]  - start flask app (manage.py:21)
[2018-11-02 09:56:14] [WARNING]  -  * Debugger is active! (_internal.py:88)
[2018-11-02 09:56:14] [INFO]  -  * Debugger PIN: 323-630-998 (_internal.py:88)

加上右对齐（左对齐一样）， [%(asctime)-15s] [%(levelname)8s] - %(message)s (%(filename)s:%(lineno)s) 得到的结果是

[2018-11-02 09:58:30] [    INFO] - start flask app (manage.py:21)
[2018-11-02 09:58:30] [ WARNING] -  * Debugger is active! (_internal.py:88)
[2018-11-02 09:58:30] [    INFO] -  * Debugger PIN: 323-630-998 (_internal.py:88)

而我想要得是

[2018-11-02 09:58:30] [INFO]    - start flask app (manage.py:21)
[2018-11-02 09:58:30] [WARNING] -  * Debugger is active! (_internal.py:88)
[2018-11-02 09:58:30] [INFO]    -  * Debugger PIN: 323-630-998 (_internal.py:88)

```python
import logging
logging.basicConfig(level=logging.DEBUG, format="%(levelname)s %(message)s")
logging.debug('it works') # DEBUG it works
logging.addLevelName(logging.DEBUG, '[my debug name]{BLANK PADDINGS}')
logging.debug('it works') # [my debug name]{BLANK PADDINGS} it works
```

你要的是"]"之后的制表符\t

最好不要用制表符自己算长度呗
类似的代码可以看 prettytable

@lolizeppelin 为何不要用制表符呢？能详细说下吗
