In our mypy config file we do not allow Any to be used. Because this cannot be avoided all the time we use #type: ignore[misc] at the top of a module.
We created a module called typing.py.
# type: ignore[misc] # Ignores 'Any' input parameter
from typing import Any, Iterable
JsonSerializable = Any
CsvSerializable = Iterable[Any]
This is imported in another module.
from my_app.typing import JsonSerializable
def foo(data: JsonSerializable) -> None:
...Actual result
PS C:\workspace\my_app> mypy
src\my_app\foo.py:6: error: Module 'my_app.typing' has no attribute 'JsonSerializable' [attr-defined]
from my_app.typing import JsonSerializable
Found 1 errors in 1 files (checked 6 source files)Expected result
PS C:\workspace\my_app> mypy
Success: no issues found in 6 source files
How did we solve it?
When we change typing.py so it ignores Any on each line we don't have any issues.
from typing import Any, Iterable
JsonSerializable = Any # type: ignore[misc] # Ignores 'Any' input parameter
CsvSerializable = Iterable[Any] # type: ignore[misc] # Ignores 'Any' input parameter
