Python 中的异常总结
User defined class
for user defined exceptions, just subclass Exception
Catching Exceptions
except Exception as e: # SystemExit, KeyboardInterrupt, GeneratorExit is not captured
log('Reason', e) # the baseline is to record
容易抛出异常的地方
- 网络读取，requests.get
- 调用其他命令超时，subprocess.call
- 读取他人的数据，IndexError
容易阻塞的地方
