How to get the errno of an IOError?


python exception errno ioerror

The Exception has an errno attribute:

try:    fp = open("nothere")except IOError as e:    print(e.errno)    print(e)

python exception errno ioerror

Here's how you can do it. Also see the errno module and os.strerror function for some utilities.

import os, errnotry:    f = open('asdfasdf', 'r')except IOError as ioex:    print 'errno:', ioex.errno    print 'err code:', errno.errorcode[ioex.errno]    print 'err message:', os.strerror(ioex.errno)

For more information on IOError attributes, see the base class EnvironmentError:

python exception errno ioerror 

try:    fp = open("nothere")except IOError as err:    print err.errno     print err.strerror
