Help with Classes

[buran]

i don't think i need a grid class since teacher told us not to use one and the set of coordinates should be saved in each class.

Yes, you can skip the Grid class, although normally you would use it. If teacher explicitly tells you not to use one, then don't

i know that triangle and sphere inherit from Shape but i dont know how to write it.it's conusing.

Fix your classes, before you do the random/grid part. For the inheritance part - take a look at this https://www.pythonforbeginners.com/super...r-function

One problem with your code as it is now - you need to pass all the necessary information when instantiate triangle or sphere (i.e. instance of the class). I mean all the information - that is, not only width, height, length or radius, but also x, y, and penalty, but also the information for the parent class - x, y and penalty. Then you will use x, y, and penalty to initialize the parent class.

teacher told ud to make it easier to fill it with objects of the characteristics example all triangles same height,width,lenght etc

That means you can define default values for these properties.
