关于异常

[cevincheung]

像这种有什么优雅的处理方法？

try..except ? 但是错误异常太多了（像这个 exc.DataError，其他的还有 OptionError ），一个个 except ?

[dawncold]

The base exception class is SQLAlchemyError. Exceptions which are raised as a result of DBAPI exceptions are all subclasses of DBAPIError.

@dawncold #1

from sqlalchemy.exc import DBAPIError, SQLAlchemyError

try:
# code
except DBAPIError:
print('dbapi')
except SQLAlchemyError:
print('sqlalchemy')


然而并没有什么事情发生
