python - Inserting while raising custom exceptions - 


if not(my_value < max_limit):     print "value of %g , hence invalid. can upto $g" % (my_value, max_limit)     raise limitfailurecheck("failed due incorrect value")

i have defined custom exception limitfailurecheck in other module. want raise when my_value > max_limt. hence have coded above method. works correctly. want ask give user more info have written print statement states problem is. can same thing while raising custom exception? tried 

raise limitfailurecheck("failed due incorrect %g value" % my_value)

but raised same statement when printed output.

raise limitfailurecheck("failed due incorrect %g value" % my_value)

i hoping 

raise limitfailurecheck("failed due incorrect 99 value")

output received:

traceback (most recent call last):   file "runtest.py", line 69, in attempt     func()   file "c:\users\pran\projects\check.py", line 66, in runmytest     raise limitfailurecheck('"failed due incorrect %g value" % my_value ) limitfailurecheck

when run python on command line , python exits due unhandled exception, python show traceback , exception string.

when run test program

class limitfailurecheck(exception):     pass  raise limitfailurecheck('i %s' % 'sad')

python says

traceback (most recent call last):   file "sad.py", line 4, in <module>     raise limitfailurecheck('i %s' % 'sad') __main__.limitfailurecheck: sad

notice python displayed line failed , failure message. if don't want behavior, can catch exception , print own message. here's script

class limitfailurecheck(exception):     pass  try:     raise limitfailurecheck('i %s' % 'sad') except limitfailurecheck, e:     print 'raise limitfailurecheck("%s")' % e

that displays 

raise limitfailurecheck("i sad")
