Is abstract class field in python possible?

I have a python programming question about testing an _init_ class?

• this is what my professor has given me Please make sure you go through each item on the checklist above before turing in your assigment. Missing items reduces your grade.　 ___1. Type in and test the Square with __init__ class from the slides ___2. Create similar class for a rectangle... name should be... you guessed it... Rectangle ___3. Attributes: x, y, width and height (must be passed into __init__), all with default values of 1 ___4. Methods: area and perimeter (not that these will use the width and height attributes) ___5. Instantiate both classes. ___6. Print the areas and perimeters of Square and a Rectangle calculated using the class methods ___7.Document your code: Every meaningful line should have documentation describing what it does. Due Date March 12, 2012 11:59:00 PM EDT this is what i have class Square: s=1 x=1 y=1 def _init_(self, x=1,y=1): self.s = x self.s = y self.s = r def area(self): return self.s*self.s def perimeter(self): return self.s*4 s = Square() s.r= 3 s.area() class Rectangle: w = 1 h = 1 r = 1 def _init_(self,w=1,h=1): self.w = w self.h = h def area(self): return self.w*self.h def perimeter(self): return self.w*2 + self.h*2 it runs with no errors.. but nothing prints out ... help appreciated

• Answer:

  I think its because you do not have print statement. To print the area of square for example you should have a statement like: print s.area() This will help you to print the value that the area function is returning. You can use print for other functions as well.
