Line is too long. Django PEP8

Question

PEP8 info:

models.py:10:80: E501 line too long (83 > 79 characters)

Models.py:

field = TreeForeignKey(\'self\', null         


        

Answer 1

This is very subjective. I'd write, if I were following E501 strictly:

field = TreeForeignKey('self',
                       null=True,
                       blank=True,
                       related_name='abcdefgh')

I usually consider 100 too long, not 80.
