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

True or False? As opposed to variables, attributes can't contain any Python object, only several selected types
False. Like variables, attributes can contain any Python object.
