While I sympathise with your circumstances we are all volunteers here so the help you receive will be at the speed that suits the members. I will address your two assignments in separate mails. > import turtle > class turtle_Turtle(): > ts = turtle.Screen() > ts.title("TurtleGTX") > bob = turtle.Turtle() > bob.shape("turtle") > bob.color("brown") I'm not sure what you think this is doing but I'm pretty sure its not what you want. You are basically defining a couple of class variables and nothing else... > class TurtleGTX(turtle_Turtle): I would have expected you to inherit from turtle.Turtle rather than turtle_Turtle. The latter has no methods and only two class variables. So your GTX class likewise has no inherited methods, you will need to define all of its behaviour. > odometer = 0 This is a class variable meaning it is shared by all turtles. I suspect you really want it to be an instance attribute, which means defined within an __init__() > def forward(x): The first parameter of a class method is usually called self because it will refer to the active object. In this case your x will be the object, whereas I think you want it to be the distance to move? But if so x is a bad choice of name since it implies horizontal direction only > if (x >= 0): > i = 0 > while (i < x): > self.fd() > odometer += 1 > i+=1 This is a horribly inefficient way of saying if x>=0: self.fd(x) odometer += x But it won't work because a) You didn't inherit from turtle so you don't have a fd() method b) Even if you had it requires an input value for its distance so should be self.fd(1) > else: > i = 0 > while (i > x): > self.bk() > odometer +=1 > i-=1 Again a very inefficient alternative to else: x = -x self.bk(x) odometer += x > print ("Odometer is", odemeter) Do you really want to print that every time the turtle moves? > my_turtle = TurtleGTX() > my_turtle.foward() You misspelled forward and failed to give it an x value. Please send real code and/or any error messages. This code could never have run so you should have errors. -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ http://www.amazon.com/author/alan_gauld Follow my photo-blog on Flickr at: http://www.flickr.com/photos/alangauldphotos _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
