python array of objects

class TestDat():          # leave this empty
    def __init__(self):   # constructor function using self
        self.Dat1 = None  # variable using self.
        self.Dat2 = None  # variable using self
    
TestArray = [] #empty array

Test1 = TestDat() #this is an object
Test2 = TestDat() #this is another object
        
Test1.Dat1 = 0 #assigning value to object 1 
Test1.Dat2 = 1 #assigning value to object 1 
    
Test2.Dat1 = 3 #assigning value to object 2 
Test2.Dat2 = 4 #assigning value to object 2

TestArray.append(Test2) #append object 2 
    
print (TestArray[0].Dat1) # this is Test1
print (TestArray[1].Dat1) # this is Test2

# or even simpler:

class TestDat():
    def __init__(self, Dat1, Dat2):
        self.Dat1 = Dat1
        self.Dat2 = Dat2

TestArray = [TestDat(0,1),

print (TestArray[0].Dat1) # this is Test1
print (TestArray[1].Dat1) # this is Test2

# or this way:

class TestDat():
    def __init__(self):
        self.Dat1 = None
        self.Dat2 = None
    
TestArray = [] #empty array
size = 2       #number of loops

for x in range(size):  # appending empty objects
    TestArray.append(TestDat())

#initialize later
TestArray[0].Dat1 = 0
TestArray[0].Dat2 = 1

TestArray[1].Dat1 = 3
TestArray[1].Dat2 = 4

print("print everithing")
for x in range(len(TestArray)):
    print("object "+str(x))
    print(TestArray[x].Dat1)
    print(TestArray[x].Dat2)
