How to print "Hello World"?
print("Hello World")
Define a class that does nothing
class SomeClass:
passTrue 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.
