When a Python segment USES try... except... After , I don’t know how to locate the detailed program crush
. These two days, the program needs to use this aspect, so I looked it up.

You need to use the Traceback package

import traceback

try:
		#Dividing by zero errors is an example
		3/0
except Exception, e:
		#This is the output for the error category, which is not really visible if the catch is a generic error
		print 'str(Exception):\t', str(Exception) #Output str(Exception): <type 'exceptions.Exception'>
		#This is the specific reason for the output error. 
		print 'str(e):\t\t', str(e) #output str(e): integer division or modulo by zero
		print 'repr(e):\t', repr(e) # Output repr(e): ZeroDivisionError('integer division or modulo by zero',)
		print 'traceback.print_exc():';    
		#Both of the following steps output the exact location of the error
		traceback.print_exc()
		print 'traceback.format_exc():\n%s' % traceback.format_exc()

In addition, Python 2.6 except after the sentence can be replaced with except Exception as e
