Making a PC Builder in Python

Building a computer is one of the many things that has been made easier than ever thanks to online part ordering websites. One important design consideration when making a PC building website is how to implement a starter kit feature where customers can start with a recommended set of parts, and swap out only specific ones as they see fit. This is great for users who aren't as tech savvy, but still have a general idea of what they'd like their new machine to do.

Desktop:

class Desktop(object):
   def __init__(self):
       self.cpu = "C1"
       self.gpu = "Inegrated Graphics"
       self.gigsOfRam = 2

   def clone(self):
       copy = Desktop()
       copy.cpu = self.cpu
       copy.gpu = self.gpu
       copy.gigsOfRam = self.gigsOfRam

       return copy

Desktop Catalogue:

class DesktopCatalogue(object):
   def __init__(self):
       self.catalogue = {}
   
   def add(self, key, prototype):
       self.catalogue[key] = prototype.clone()
   
   def getComputer(self, key):
       if key in self.catalogue:
           return self.catalogue[key].clone()
       else:
           raise ValueError(key)

Demo:

catalogue = DesktopCatalogue()

# Create a basic setup:
basicWorkstation = Desktop()
basicWorkstation.cpu = "j5"
basicWorkstation.gpu = "cornea Graphics 9001"
basicWorkstation.gigsOfRam = 4

catalogue.add("Everyday Computing", basicWorkstation)

# Now a more advanced setup:
gamingSetup = Desktop()
gamingSetup.cpu = "X1 Hyper Thread"
gamingSetup.gpu = "Hive 7series"
gamingSetup.gigsOfRam = 1024

catalogue.add("Gaming", gamingSetup)

# Using the Prototypes:
myBasicComputer = catalogue.getComputer("Everyday Computing")
# Add some more ram to get more use out of it:
myBasicComputer.gigsOfRam = 8

# Let's make a big super computer next:
mySuperComputer = catalogue.getComputer("Gaming")

mySuperComputer.gigsOfRam = 4096
mySuperComputer.cpu = "Octa-Streamed X1 Giga Thread"
mySuperComputer.gpu = "Quad Hive 9series"
