1. Create a directory and name it Cars
   [all the following modules will be placed in this dir.]

2. Then create the first 3 modules.  
   [Create the file named Bmw.py]

#Bmw.py in Cars
# Python code to illustrate the Modules
class Bmw:
    # First we create a constructor for this class
    # and add members to it, here models
    def __init__(self):
        self.models = ['i8', 'x1', 'x5', 'x6']
    #def end
    # A normal print function
    def outModels(self):
        print('These are the available models for BMW')
        for model in self.models:
            print('\t%s ' % model)
	#for end
    #def end
#class end

#Audi.py in Cars
# Python code to illustrate the Module
class Audi:
    # First we create a constructor for this class
    # and add members to it, here models
    def __init__(self):
        self.models = ['q7', 'a6', 'a8', 'a3']
    #def end
    # A normal print function
    def outModels(self):
        print('These are the available models for Audi')
        for model in self.models:
            print('\t%s ' % model)
	#for end
    #def end
    def outModel_a8(self):
        print('These are the available models for Audi')
        for model in self.models:
            if model=='a8':
                print('\t%s ' % model )
            #if end
	#for end
    #def end

#class end

#Nissan.py in Cars
# Python code to illustrate the Module
class Nissan:
    # First we create a constructor for this class
    # and add members to it, here models
    def __init__(self):
        self.models = ['altima', '370z', 'cube', 'rogue']
    #def end
    # A normal print function
    def outModels(self):
        print('These are the available models for Nissan')
        for model in self.models:
            print('\t%s ' % model)
	#for end
#class end

#__init__.py in Cars (can be empty)
from Bmw import Bmw
from Audi import Audi
from Nissan import Nissan


#sample.py
# Import classes from your brand new package
from Cars import Bmw
from Cars import Audi
from Cars import Nissan
   
# Create an object of Bmw class & call its method
ModBMW = Bmw()
ModBMW.outModels()
   
# Create an object of Audi class & call its method
ModAudi = Audi()
ModAudi.outModels()
  
# Create an object of Nissan class & call its method
ModNissan = Nissan()
ModNissan.outModels()


#getbuyProgram.py
#from Cars.Audi.a8 import get_buy

#Now call the function from anywhere:
get_buy(1)

print("end of getbuyProgram.py")
#end of getbuyProgram.py

Title: This worked for Thonny 
  as of 2022BFeb23
  I am still modifying it replacing Cars with IX
Thonny uses its own virtual environment by default. Open 
"Tools => Manage packages" or "Tools => Open system 
shell" in order to install into this environment. For 
completeness I will add that once you are in the 
Thonny System Shell you can run either "pip" or "pip3" 
to install the module you need.
1. Tell Thonny to include the Tools menu
2. Restart Thonny, then click on "Tools"
3. Select "Manage Packages"
4. Read "Target: user site packages
     from /home/pi/.local/lib/python3.7/site-packages
   This dialog lists all available packages, but allows 
   upgrading and uninstalling only packages from 
   /home/pi/.local/lib/python3.7/site-packages . 
   New packages will be also installed into this 
   directory. Other locations must be managed by 
   alternative means.
