If this provides you an error message on the specific key that’s missing
```
class User:
profile = None
u = User()
u.profile.name # AttributeError: None does not have attribute name
```
Then may I suggest that this has the same ?
```
user = {
“profile”: None
}
user[“profile”][“name”] # TypeError: None is not subscripable
```
Currently doesn’t indicate which key triggered this which isn’t helpful in
software that will send the high level exception message to you.
There has been recent discussion in the null operator thread that statements
like this should always make clear which part failed
But python even today doesn’t always do this
