Check if a set of key/values in dict list is in another list - list

Question

I have a list as follows:
[
{
'Name': 'Name1',
'Address': 'Address1'
},
{
'Name': 'Name2',
'Postcode': 'MyPostcode'
}
]
And another list like this:
[
{
'Name': 'Name1',
'data' : {
'Address': 'Address1',
'Postcode': 'Whatever'
},
{
'Name': 'Name2',
'data' : {
'Address': 'Whatever',
'Postcode': 'MyPostcode'
},
{
'Name': 'Name3',
'data' : {
'Address': 'Whatever',
'Postcode': 'Whatever'
},
]
For any of the items in the first list, I need to check if that combination of key/value exists in the second, and if so, delete it from the second
I can do it in multiple lines of codes, with different for loops, but probably there is a wiser way of doing it. Can anybody suggest an elegant solution?
In the example above, it should delete the two first dicts from the list and return a list only with the third one
[
{
'Name': 'Name3',
'data' : {
'Address': 'Whatever',
'Postcode': 'Whatever'
}
]
Thanks

Try:
lst1 = [
{"Name": "Name1", "Address": "Address1"},
{"Name": "Name2", "Postcode": "MyPostcode"},
]
lst2 = [
{"Name": "Name1", "data": {"Address": "Address1", "Postcode": "Whatever"}},
{
"Name": "Name2",
"data": {"Address": "Whatever", "Postcode": "MyPostcode"},
},
{"Name": "Name3", "data": {"Address": "Whatever", "Postcode": "Whatever"}},
]
out = []
for d2 in lst2:
t = set({"Name": d2["Name"], **d2["data"]}.items())
for d1 in lst1:
if t.issuperset(d1.items()):
break
else:
out.append(d2)
print(out)
Prints:
[{'Name': 'Name3', 'data': {'Address': 'Whatever', 'Postcode': 'Whatever'}}]
