“ConfigParser” has no attribute “readfp”

[remdragon]

I was told this error might be a bug in typeshed:

https://stackoverflow.com/questions/50302677/mypy-error-configparser-has-no-attribute-readfp?noredirect=1#comment87627773_50302677

When I run this command, I get no errors:

mypy --py2 test.py

but when I run this:

mypy test.py

I get this:

test.py:6: error: "ConfigParser" has no attribute "readfp"

Here's test.py, it runs correctly in both py2 and py3:

from io import open
from six.moves import configparser

cfg = configparser.ConfigParser()
with open ( 'test.ini', 'r', encoding='utf-8', errors='strict' ) as f:
    cfg.readfp ( f )
assert cfg.get ( 'foo', 'bar' ) == 'hello'
