Line continuation and comments

I haven’t seen that one. What I get is warnings about:

def is_adult( self )->bool:
    LEGAL_AGE_US = 21
    return LEGAL_AGE

It doesn’t like LEGAL_AGE_US being all caps if declared in a function.

Alternative to suggestions thus far: break the complex* logical
condition into 'labelled' components, and then combine those (likely
shorter) into the condition:

if person.is_adult and person.is_qualified and person.has_funds ...

which presumes that at some previous time we have, for example:

def is_adult( self )->bool:
     return 21 <= self.age <= 65

(not that I'd like to see those two 'magic-constants' in anyone's code,
but (hopefully) the idea has been conveyed...)


* "simple is better than..."
