Python Write Better Python Cleaner Code PEP 8

Managing whitespace, how do the pros do it?

I noticed when I ran Flake8 on my code, Flake8 flagged several cases where I had extra whitespace in places where it did not belong, but Kenneth's badpep8.py file contained none of these whitespace mistakes. Is there something he and other experienced Pythonistas are doing to consistently avoid this issue? That is, how is Kenneth systematically avoiding accidentally leaving extra whitespace in places it doesn't belong without having to think about it? Clearly I have some bad habits right now when it comes to typing and navigating the page with the cursor because I had about 8 of these errors.

IDE editors usually include a syntax checker that constantly checks the syntax as you type. Vim, Emacs, PyCharm, Eclipse all have Python modes.

I like to run Emacs with a mode that automatically cleans up (“lints”) the code upon saving.

Thank you Chris Freeman . I found this distressing because these errors are invisible to the eye so it's good to know I don't have to look for them manually.
