|

class Foo:
|
||||
_bar = 42
|
||||
|
||||
print(Foo.bar) # error: [unresolved-attribute]
|
||||
```
|
||||
|
||||
The suggestion is not suppressed if the typo itself starts with a leading underscore, however:
|
||||
|
||||
```py
|
||||
print(Foo._barr) # error: [unresolved-attribute]
|
||||
```
|
||||
|
||||
And in method contexts, the suggestion is never suppressed if accessing an attribute on an instance
|
||||
of the method's enclosing class:
|
||||
|
||||
```py
|
||||
class Bar:
|
||||
_attribute = 42
|
||||
|
||||
def f(self, x: "Bar"):
|
||||
# TODO: we should emit `[unresolved-attribute]` here, should have the same behaviour as `x.attribute` below
|
||||
print(self.attribute)
|
||||
|
||||
# We give a suggestion here, even though the only good candidates start with underscores and the typo does not,
|
||||
# because we're in a method context and `x` is an instance of the enclosing class.
|
||||
print(x.attribute) # error: [unresolved-attribute]
|
||||
|
||||
class Baz:
|
||||
def f(self, x: Bar):
|
||||
# No suggestion is given here, because:
|
||||
# - the good suggestions all start with underscores
|
||||
# - the typo does not start with an underscore
|
||||
# - We *are* in a method context, but `x` is not an instance of the enclosing class
|
||||
print(x.attribute) # error: [unresolved-attribute]
|
||||
```

## `from` import that has a typo
|
||||
|
||||
We offer a "Did you mean?" subdiagnostic suggestion if there's a name in the module that's
|
||||
reasonably similar to the unresolved member.
|
||||
|
||||
<!-- snapshot-diagnostics -->
|
||||
|
||||
`foo.py`:
|
||||
|
||||
```py
|
||||
from collections import dequee # error: [unresolved-import]
|
||||
```
|
||||
|
||||
However, we suppress the suggestion if the only close matches in the module start with a leading
|
||||
underscore:
|
||||
|
||||
`bar.py`:
|
||||
|
||||
```py
|
||||
from baz import foo # error: [unresolved-import]
|
||||
```
|
||||
|
||||
`baz.py`:
|
||||
|
||||
```py
|
||||
_foo = 42
|
||||
```
|
||||
|
||||
The suggestion is never suppressed if the typo itself starts with a leading underscore, however:
|
||||
|
||||
`eggs.py`:
|
||||
|
||||
```py
|
||||
from baz import _fooo # error: [unresolved-import]
