Question

Given this Python class, implementing a Django form, how would you properly break this to meet the PEP8 standards?

class MyForm(forms.Form):
    categories = forms.CharField(required=False,
                                 widget=forms.SelectMultiple(choices=CATEGORY_VALUE),                                               
                                 label="Categories")
    additional_item_ship_cost = forms.CharField(required=False, max_length=10,                                                      
                                                label="Additional Item Ship Cost")

Specifically, the widget= and label= parameters violate the PEP8 rules for line length.

What comes to mind immediately is that I could define the widget and label outside of the class and then use them in the class definition, but that feels very un-pythonic.

I don’t think PEP8 says much about it, but I would simply go with double indentation for the parameters:

class MyForm(forms.Form):
    categories = forms.CharField(
            required=False,
            widget=forms.SelectMultiple(choices=CATEGORY_VALUE),
            label="Categories"
        )
    additional_item_ship_cost = forms.CharField(
            required=False,
            max_length=10,
            label="Additional Item Ship Cost"
        )
