[code-quality] Questions: Flake8-2.4.1

Just installed flake8-2.4.1. Checking a file generates this error: pwschemasl.py:698:39: E225 missing whitespace around operator on this line: rpt_filename=Column(BLOB, nullable=False) where position 39 is 'F'. So, I add the space: rpt_filename=Column(BLOB, nullable= False) and now flake8 shows this error: pwschemasl.py:698:40: E251 unexpected spaces around keyword / parameter equals This is an infinite loop that affects many lines of code in the file. The lines throw a PEP8 compliance error both with and without a space following the '=' sign. Is there something I've done incorrectly that I don't see? Puzzled, Rich
