Chained method calls indentation style in Python [duplicate]
This is a case where a line continuation character is preferred to open parentheses.
ShortName.objects.distinct() \ .filter().values() # looks better
The need for this style becomes more obvious as method names get longer and as methods start taking arguments:
return some_collection.get_objects(locator=l5) \ .get_distinct(case_insensitive=True) \ .filter(predicate=query(q5)) \ .values()
PEP 8 is intend to be interpreted with a measure of common-sense and an eye for both the practical and the beautiful. Happily violate any PEP 8 guideline that results in ugly or hard to read code.
That being said, if you frequently find yourself at odds with PEP 8, it may be a sign that there are readability issues that transcend your choice of whitespace :-)
I think the best is to use () to force line joining, and to do this:
(ShortName.objects.distinct() # Look ma! .filter(product__photo__stickitem__isnull=False) # Comments are allowed .values_list('value', flat=True))
It's not ideal, but I like that it stands out visually and makes it somewhat obvious what the chain of calls is. It allows end-of-line comments, which
\ newline does not.
