Python extending with - using super Python 3 vs Python 2

Question

Originally I wanted to ask this question  but then I found it was already thought of before    Googling around I found this example of extending configparser  The following works with Python 3    python3 Python 3 2 3rc2  default  Mar 21 2012  06 59 51    GCC 4 6 3  on linux2  gt  gt  gt  from configparser import  SafeConfigParser  gt  gt  gt  class AmritaConfigParser SafeConfigParser           def   init   self               super     init           gt  gt  gt  cfg   AmritaConfigParser    But not with Python 2   gt  gt  gt  class AmritaConfigParser SafeConfigParser             def   init   self                 super SafeConfigParser  init         gt  gt  gt  cfg   AmritaConfigParser   Traceback  most recent call last     File  quot  lt stdin gt  quot   line 1  in  lt module gt    File  quot  lt stdin gt  quot   line 3  in   init   TypeError  must be type  not classob  Then I read a little bit on Python New Class vs  Old Class styles  e g  here  And now I am wondering  I can do  class MyConfigParser ConfigParser ConfigParser         def Write self  fp              quot  quot  quot override the module s original write funcition quot  quot  quot                       def MyWrite self  fp              quot  quot  quot Define new function and inherit all others quot  quot  quot   But  shouldn t I call init  Is this in Python 2 the equivalent   class AmritaConfigParser ConfigParser SafeConfigParser        def   init   self            super     init       Python3 syntax  or rather  new style class syntax                 is this the equivalent of the above        def   init   self           ConfigParser SafeConfigParser   init   self

super    without arguments  was introduced in Python 3  along with   class      super   - gt  same as super   class    self    so that would be the Python 2 equivalent for new-style classes   super CurrentClass  self   for old-style classes you can always use    class Classname OldStyleParent       def   init   self   args    kwargs           OldStyleParent   init   self   args    kwargs
