对于一些代码如下, 如何以我自己的方式处理python生成的错误消息?
opts, args = getopt.getopt(sys.argv[1:], "c:", ... for o,v in opts: ... elif o in ("-c", "--%s" % checkString): kCheckOnly = True clientTemp = v
如果我不给-c之后的参数,我得到的错误信息如下。
Traceback (most recent call last): File "niFpgaTimingViolationMain.py", line 100, in opts, args = getopt.getopt(sys.argv[1:], "hdc:t:",[helpString, debugString, checkString, twxString]) File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/getopt.py", line 91, in getopt opts, args = do_shorts(opts, args[0][1:], shortopts, args[1:]) File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/getopt.py", line 195, in do_shorts opt) getopt.GetoptError: option -c requires argument
有没有办法赶上这个错误,并处理它打印这样的事情?似乎只是在try/wrap中包装代码不起作用。
ERROR: You forgot to give the file name after -c option
try-except子句不能正确工作吗? – SilentGhost 2010-04-06 15:00:34
我弄错了,jemfinch给出了正确的例子。 – prosseek 2010-04-06 15:24:57
