# How do we indent long lines

# Example one
# Too long
fields = ('slug', 'name', 'description', 'start_date', 'end_date')

# If you're just over 80 characters, you can do this, it's the simplest
# form of satisfying the 80 character max
fields = (
    'slug', 'name', 'description', 'start_date', 'end_date')


# If you're way over 80 characters, you have to move each element to its own line like this
fields = (
    'slug',
    'name',
    'description',
    'start_date',
    'end_date', # always include a trailing comma, they're legal and make refactoring easier
)

# I do not like tooth brush indentation
fields = ('slug', 'name', 'description',
          'start_date', 'end_date')

# because it makes refactoring later harder, for instance if you change the name `fields` 
# now you have to change the indentation on the following line, 
# or if you want to add a new field name or change the order of them
# then you have to move every line around

I've seen people do:

birds = Bird.objects.all().filter(cute=True).order_by('this',
                                                      'that',
                                                      'the other',
                                                      'like....seriously?')
