class definition syntax

[harryos]

hi
i have seen some class definitions like

class MyClass(object) :
def __init__(self):
....

what does the object keyword inside the braces in MyClass() mean?
Has it got any significance?

thanks in advance
harry

It indicates a so-called new-style-class. The new style classes have been
available since python2.2:

It's inheritance. MyClass class inherits from object class.
Check out point 9.5 in the tutorial.

It is a syntax used for 'new type' classes, not so new any more.

If you google that phrase, you get many references.

Here is a tutorial dating back to 2005.

It's not a keyword.

inside the braces in MyClass() mean?

Answer is here:

Nope, why ? It just look better that way...

Harry, this neswgroup is - as you may have noticed by now - very newbie
friendly. But this is not a reason for not reading *at least* the
FineManual's tutorial.
