Python Oserror Error Number
Contents |
This module makes available standard errno system symbols. The value of each symbol is the corresponding integer value.
Python Errno
The names and descriptions are borrowed from linux/include/errno.h, which python filenotfounderror should be pretty all-inclusive. errno.errorcode¶ Dictionary providing a mapping from the errno value to the python custom exception string name in the underlying system. For instance, errno.errorcode[errno.EPERM] maps to 'EPERM'. To translate a numeric error code to an error message, use

os.strerror(). Of the following list, symbols that are not used on the current platform are not defined by the module. The specific list of defined symbols is available as errno.errorcode.keys(). Symbols available can include: errno.EPERM¶ Operation not permitted errno.ENOENT¶ No such file or directory errno.ESRCH¶ No such process errno.EINTR¶

Most Exceptions in Python don't have "error numbers". One exception (no pun intended) are HTTPError exceptions, for example: import urllib2 try: page = urllib2.urlopen("some url") except urllib2.HTTPError, err: if err.code == 404: print "Page not found!" else: ... Another exception (as noted by bobince) are EnvironmentErrors: import os try: f=open("hello") except IOError, err: print err print err.errno print err.strerror print err.filename outputs [Errno 2] No such file or directory: 'hello' 2 No such file or directory hello share|improve this answer edited Jul 15 '10 at 14:41 answered Jul 13 '10 at 21:08 Tim Pietzcker 197k27263354 This was exactly what I was looking for!

That expresion catches two types of exception; OSError or whatever the global e refers to. Your code breaks when there is no global name e. The correct expression for Python 3 and Python 2.6 and newer is: except OSError as e: Python 2 also supports the syntax: except OSError, e: without parenthesis, or: except (OSError, ValueError), e: to catch more than one type. The syntax was very confusing, as you yourself discovered here. The change was added in Python 2.6 and up, see PEP 3110 - Catching Exceptions in Python 3000 and the Exception-handling changes section of the 2.6 What's New document. As for an exception for errno.EPERM; you didn't import errno, so that is a NameError as well. share|improve this answer edited Dec 11 '13 at 11:30 answered Dec 11 '13 at 11:24 Martijn Pieters♦ 502k7513181473 Missed import errno as well, that was the root cause and again a stupid question on my part which i spent a few hours on.. What's the difference between (OSError, e) and X as Y? Edit: Thanks for clairifying the syntax of it! –Torxed Dec 11 '13 at 11:25 1 @Torxed: except X, Y (without parenthesis) was replaced by except X as Y, because

So I tried this: PHP Code: importos
But I still get the same exact error message. I know that I can catch the error by doing either of the following: PHP Code:
try:
os.rmdir("/home/user/Desktop/NewFolder")
exceptos.errno.ENOTEMPTY:
print"Directorynotempty"
except:
