Learn to Program: Crafting Quality Code

Screenshot

enter image description here This is a video lecture from Coursera Learn to Program Crafting Quality Code Course. So there is a quiz during the video.

class MyInt(int):
    # some code there

They gave 4 answers where I need to choose a right one. I've choose my answers one by one but finally they say that right is absolutely wrong answer.

int is a subclass of MyInt

This question Python: How do I make a subclass from a superclass? gives me absolutely right confirmation that I'am right.

Where is the truth?

There must be something wrong with the quiz, the code as written in the question is declaring that MyInt is a subclass of int (or equivalently: that int is the superclass of MyInt), no the other way around.

If you inherit from a class, that class is the super-class. In the example int is the super (or base) class and MyInt is the subclass. They're wrong, just as you suspected. ;-)

  • Thanks. # I was not suspecting. :) I'm just boring to watch the videos only to get a certificate. I prefer to learn the core of the language or a technology on their main site. – user1667218 Apr 11 '13 at 16:53
