In this exercise, it states that
dir() can be called on an object to investigate its attributes. Can
dir() also be called on a class?
Yes, you can use
dir() to examine a class in addition to calling it on an object of a class. In the following code example, you can see that the
dir() call on the object of class
Examine shows the instance variable created in the object while the call for the class does not.
class Examine: class_var = "This is a class variable" def __init__(self): self.inst_var = "This is an instance variable" myobj = Examine() print(dir(Examine)) # OUTPUTS: ['__doc__', '__init__', '__module__', 'class_var'] print(dir(myobj)) # OUTPUTS: ['__doc__', '__init__', '__module__', 'class_var', 'inst_var']
