Python Web Development Techdegree Student 8,420 PointsWhy not put "def __init__" before other methods in character.py?
In Kenneth's code for the Character class (character.py), he put the def __init__
method below the methods attack()
and get_weapon(self)
. This looks funny to me -- funny/strange, not funny/ha-ha (highly technical phrasing, I know).
If I understand correctly, when a instance of a class is created, the order in which the methods were written in the underlying .py file isn't always crucial. However, wouldn't this particular code look cleaner and be easier to read if def __init__(self, **kwargs)
were the first method (after any defaults are declared, of course) that we come across in the Character class definition?
In general, when writing a class, shouldn't the__init__
method come before any other methods within the class? Not for the sake of functionality, but for readability?

231,271 PointsIt makes sense to me also, but I checked the PEP8 and didn't find it in there. It did say that module-level "dunder" names should come before others, and before imports. But no mention of method-level names.
So I guess it's not generally considered that important. Seems like it would be a good practice though.

12,885 PointsIt doesn't matter where we put our methods in the class as long as it doesn't cause errors. As python is interpreted language (code is executed line by line). So, the methods which call another method must come after. For example:
def A(): #some code def B(): A() #some code
Thus, if B() is calling A(), so it must come after A(). So is the case with all the method calling. It doesn't matter where we put int() methods (magical methods) as long as they obey calling procedures.
I hope this solves the issue.

9,856 Points@ Jeff Hartl. I too had this question and concern. I think it is good practice to always define init(self): as the first method after creating a Class. I usually think of it as the 'Boot up sequence' if you will. While apparently not necessary to be first, I think it does have a much cleaner and neater look or "Readability", like you said. Great question Jeff.
