def handleValueError():
flag = False
startdate = None
enddate = None
err_msg = traceback.format_exc()
index = err_msg.find('Value')
print err_msg[index:]
return (flag,startdate,enddate)
And in your code above:
except ValueError:
return handleValueError()

Just use try/except as usual. There is no difference
to exceptions thrown by your code and the ones thrown
by the standard Python functions. Consider:
####### module.py #######
def f():
raise ValueError
##########################
###### main.py ##########
import module
try:
module.f()
except ValueError:
print "It broke!"
#########################
Is that clear?
