flake8 personal setting for python

When I code python programs using emacs, emacs uses elpy and elpy uses flake8 for syntax checking. But this syntax checking is kind of annoying. For example, I would like to write like this

x = some_func(a,b,c+d)

instead of this

x = some_func(a, b, c + d)

I think this style condtains too many whitespaces which make code lengthy.

To change the style in flake8, you can write the following lines in ~/.config/flake8 :

[flake8]
ignore = E226, E231

To be honest, I forget what those E226 and E231 means (one can google them) but at least you can change the syntax style by doing this.
