Questions

Hello World

How to print "Hello World"?

print("Hello World")

Classes

Define a class that does nothing

class SomeClass:
    pass

True or False? If c is an instance of a class, then in c.x = 1, x is a variable of the value 1

False. x is an attribute in the case c.x = 1

True or False? Every object in Python has attributes

True. You can think on attributes as private dictionaries but instead of accessing them with [] or .get, they are accessed by using a dot.
