Build class to make a Smart list - trying

[icm63]

Getting there

my class

import datetime as dt


class Defaults:
    """Exaample of Storage of Default Values"""

    dbConStr = "pass:Name:Database;"
    baseDate = dt.datetime(2000,12,31)
    baseVal = int(100)


class myStructure:
    """ My custom data structure for arrays """

    def __init__(self, date1=dt.datetime(2000,12,31), num1=0, str1="Nothing"):
        self.date1 = date1
        self.num1 = num1
        self.str1 = str1

        

class MySmartList():
        """ Smart list with field data IDs """

        def __init__(self): 
            self.data0 =[]

        #Add new records to data0 list via data structure object
        def AddNewRec(self,date1="05/01/1950", num1=0, str1="Nothing"):
            #Accepted date format 05/01/1950
            zDate = dt.datetime.strptime(date1,"%m/%d/%Y")
            self.data0.append(myStructure(zDate, num1, str1))

My smart list with a structure

myData=my.MySmartList()
myData.AddNewRec(date1 = "05/01/1950",num1=100,str1='Test0')
myData.AddNewRec(date1 = "05/02/1950",num1=101,str1='Test1')
myData.AddNewRec(date1 = "05/03/1950",num1=102,str1='Test2')


for index, myData in enumerate(myData):
   print(index, myData.str1 +  ' -- '  + str(myData.num1)  + ' -- ' + str(myData.date1))

Error on this line: for index, myData in enumerate(myData):

Traceback (most recent call last):
File "C:\Users\RTT\Documents\Visual Studio 2017\Projects\Python_Test_Project\Python_Test_Project\Test1.py", line 54, in <module>
for index, myData in enumerate(myData):
TypeError: 'MySmartList' object is not iterable

any ideas?
