Instance of 'OpenFiles' has no 'path' member (no-member)

[mxmlnkn]

Hi,

I'm trying to use fsspec, but I cannot convince pylint of the correctness of my program:

import fsspec
file = fsspec.open("foo")
print(file.path)

Calling pylint test.py yields:

test.py:1:0: C0114: Missing module docstring (missing-module-docstring)
test.py:4:6: E1101: Instance of 'OpenFiles' has no 'path' member (no-member)

For some reason, pylint seems to think that open returns OpenFiles, but it actually returns OpenFile. Could it be that the type information is somehow incorrect? The program runs fine, so it definitely is a false positive.

Certainly can be. In fact, the function is not typed. It returns fsspec.open_files(...)[0], i.e., OpenFiles[0]. getitem on OpenFiles can return OpenFiles for a slice, or a single OpenFile for an integer. Make of that what you like.
