Best practice for Python 3 class creation

Question

In my research I found that in Python 3 these three types of class definition are synonymous:

class MyClass:
    pass

class MyClass():
    pass

class MyClass(object):
    pass

However, I was not able to find out which way is recommended. Which one should I use as a best practice?

Answer 1

I would say: Use the third option:

class MyClass(object):
    pass

It explicitly mentions that you want to subclass object (and doesn't the Zen of Python mention: "Explicit is better than implicit.") and you don't run into nasty errors in case you (or someone else) ever run the code in Python 2 where these statements are different.
