This class allows creation of Dynamic Nested dictionaries, and includes a formatted print routine for same.
The built in example 'testit' builds the following dictionary dynamically:
CityList = {
'Boston': {
'Resturants': {
'Spoke Wine Bar': {
'Addr1': '89 Holland St',
'City': 'Sommerville',
'ZipCode': '02144',
'Phone': '617-718-9463'
},
'Highland Kitchen': {
'Addr1': '150 Highland Ave',
'City': 'Sommerville',
'ZipCode': '02144',
'Phone': '617-625-1131'
}
}
}
}
The code is simple:
