pro*_*eek 8 python error-handling
考虑我用来检查存储的错误消息的try/catch块e.
equeryString = "SELECT * FROM benchmark WHERE NOC = 2"
try:
res = db.query(queryString)
except SQLiteError, e:
# `e` has the error info
print `e`

e这里的对象只包含上面的字符串.但是,当python报告未处理的错误时,它会显示一个非常详细的信息,如下所示:
Traceback (most recent call last):
File "fool.py", line 1, in
open("abc.zyz", "r")
IOError: [Errno 2] No such file or directory: 'abc.zyz'
我的问题是,如何获取上述信息(文件和行号等)?或者,如果e包含此信息,它是如何存储在其中的?

这将显示错误的跟踪.
import traceback
try:
res = db.query(queryString)
except SQLiteError, e:
# `e` has the error info
print `e`
for tb in traceback.format_tb(sys.exc_info()[2]):
print tb
