Calling a class method raises a TypeError in Python

Question

I don\'t understand how classes are used. The following code gives me an error when I try to use the class.

class MyStuff:
    def average(a, b, c): # Get th

To minimally modify your example, you could amend the code to:

class myclass(object):
        def __init__(self): # this method creates the class object.
                pass

        def average(self,a,b,c): #get the average of three numbers
                result=a+b+c
                result=result/3
                return result


mystuff=myclass()  # by default the __init__ method is then called.      
print mystuff.average(a,b,c)

Or to expand it more fully, allowing you to add other methods.

class myclass(object):
        def __init__(self,a,b,c):
                self.a=a
                self.b=b
                self.c=c
        def average(self): #get the average of three numbers
                result=self.a+self.b+self.c
                result=result/3
                return result

a=9
b=18
c=27
mystuff=myclass(a, b, c)        
print mystuff.average()
