The difference and connection between python3 and python2 exception handling

In python2.x, exceptions are handled like this. Add a comma "," after the exception base class and then follow the exception type

import traceback

try:
  1/0
except Exception , err:
  print err
 

In python3.x, exceptions are handled like this. The base class connects the exception type through the keyword "as"

import traceback

try:
  1/0
except Exception as err:
  print(err)
