method call help

[noisefloor]

Hi,

I want to develop function pricing_intel() and pricing_mac(), which defines the price of each detail of employee who do , the price of intel material different from mac price

I still don't get the point... As far as I can see, what you call "price" is some type of base price or factor. As the price is a class variable, you can simple overwrite it. Howerver, your quite complicated (most likely overcomplicated) class design and inheritance makes it extremly hard to trace where something is overwritten (or not).
