Spyder gives wrong information about PEP8 with annotations

[Martmists-GH]

Description of your problem

Spyder recommends no whitespace around kwargs when there are type annotations, but according to PEP 8 there should be:

When combining an argument annotation with a default value, use spaces around the = sign (but only for those arguments that have both an annotation and a default).

Yes:

def munge(sep: AnyStr = None): ...
def munge(input: AnyStr, sep: AnyStr = None, limit=1000): ...

No:

def munge(input: AnyStr=None): ...
def munge(input: AnyStr, limit = 1000): ...

What steps will reproduce the problem?

def func(arg, kwarg: str=None):  # Good according to spyder
    return "This is bad according to PEP 8"

def func(arg, kwarg: str = None):  # Shows an exclamation mark
    return "This is good according to PEP 8"

This is not under Spyder control, i.e. Spyder only parses and reports warnings generated by the pep8, and once 3.2 is released, pycodestyle packages.

So I think you should report this issue in the pycodestyle repository.

[Martmists-GH]

After checking the file with pycodestyle file.py, it seems nor pycodestyle, nor flake8 nor pylint cause that error in that file, despite that error still being there in Spyder.

If you put the mouse over the exclamation marker what is the message?

Maybe It was generated for pyflakes (the example that you mention will cause a warning for the redefiinition of func)

[Martmists-GH]

E251 Unexpected spaces around keyword / parameter equals

[Martmists-GH]

Just did a quick check, the error is thrown by the pep8 module. I'm assuming this issue is deprecated then and I'll just have to wait for pep8 to be replaced by pycodestyle as soon as possible.

[rlaverde]

Ohh I see, so this error is related to #3197, that has already been fixed, and will be part of Spyder 3.2

[Martmists-GH]

The 3.2 milestone was planned for the day after tomorrow? I somehow feel like they're not going to reach it ;) Until then I'll just ignore this error and use pycodestyle manually I guess
