[Tutor] die or exit function?

[doug shawhan]

Hi Andy,

Putting a try:/except: loop in your __main__() (or whatever you call
your base function) with sys.exit("Message") is pretty much the way I
always do it.

try:
    gak = puke + die
except:
    sys.exit("Oy!")

If you would like sys.exit() to provide you with a bit more
information (like what actually happened during the failure and
where!) I found this handy function:


def formatExceptionInfo(maxTBlevel=5):
	cla, exc, trbk = sys.exc_info()
	excName = cla.__name__
	try:
		excArgs = exc.__dict__["args"]
	except KeyError:
		excArgs = "<no args>"
	
	excArgsString = ''
	for item in excArgs:
		excArgsString = excArgsString + ' ' + str(item)
	
	excTb = traceback.format_tb(trbk, maxTBlevel)
	excTbString = ''
	for item in excTb:
		excTbString = excTbString + " " + str(item)
	
	report = "%s %s %s"%(excName, excArgsString, excTbString)
	return(report)

This function now goes in most of what I do that requires error reporting.

Hope this helps!
