[Python] Merging lists of dictionaries based on nested list values

I'm struggling to create a new list based on two input lists. Here's an example:

data_1 = [
{
"title": "System", "priority": "medium", "subtitle": "mason",
"files": [
{"name": "mason", "path": "/tmp/mason/mason.json"},
{"name": "mason", "path": "/tmp/mason/build.json"}
]},
{
"title": "System", "priority": "medium", "subtitle": "kylie",
"files": [
{"name": "kylie", "path": "/tmp/kylie/build.tar"},
{"name": "kylie", "path": "/tmp/kylie/kylie.json"}
]}
]

data_2 = [
{
"title": "System", "priority": "medium",
"files": [
{"name": "build", "path": "/tmp/kylie/build.tar"},
{"name": "kylie", "path": "/tmp/kylie/kylie.json"},
{"name": "mason", "path": "/tmp/mason/mason.json"},
{"name": "build", "path": "/tmp/mason/build.json"}
]}
]

merged = [
{
"title": "System", "priority": "medium", "subtitle": "mason",
"files": [
{"name": "mason", "path": "/tmp/mason/mason.json"},
{"name": "build", "path": "/tmp/mason/build.json"}
]},
{
"title": "System", "priority": "medium", "subtitle": "kylie",
"files": [
{"name": "build", "path": "/tmp/kylie/build.tar"},
{"name": "kylie", "path": "/tmp/kylie/kylie.json"}
]}
]


Basically, it would be OK to keep data from data_1 list and just replace files.name with the names coming from data_2 list, having the same path. Or multiply the element in data_2, assigning a subtitle and deleting all data_2.files items that don't match the paths specified in data_1 list.

Anyway, I started doing something like:

for d1 in data_1:
for d2 in data_2:
d1_key = (d1.get("title"), d1.get("priority"))
d2_key = (d1.get("title"), d1.get("priority"))
if d1_key == d2_key:
for df in d1.get("files"):
if any(df.get("path") in entry.get("path") for entry in d2.get("files")):
print("Help! There must be easier way!")


And I don't think it's clear enough to get into this further.

Would you suggest any other way to get the merged list created?
