Help with self.

[tomX]

Hello everyone!

I'm relatively new to OOP and I'm getting the error

NameError: name "self" is not defined

. I'm trying to program a seven-segment display kinda thing. Do I need all the self in the List? Without them it said, that pos is not defined...
Here's the code:

from Segment import Segment

class SevenSegments:
    margin = 20
    Segment = Segment(0, 0, 0, False)
    pos = [[self.Segment.w+(2*margin), margin, 90], 
        [self.pos[0][0] + self.Segment.h+self.margin, 2*self.margin+self.Segment.w, 0], 
        [self.pos[0][0] + self.Segment.h+self.margin, 3*self.margin+self.Segment.w+self.Segment.h, 0], 
        [self.pos[0][0], self.pos[2][1]+self.margin+self.Segment.w, 90], 
        [self.margin, 3*self.margin+self.Segment.w+self.Segment.h, 0],
        [self.margin, 2*self.margin+self.Segment.w, 0],
        [self.Segment.w +2*self.margin, self.Segment.h+self.Segment.w+2*self.margin, 90]]
    number = 0,
    def __init__(self, num):
        number = num

    def update(self):
        for i in self.self.pos:
            s = Segment(self.pos[i][0], self.pos[i][1], self.pos[i][2], True)
            s.show()
            
    

If you need to have all the files, here's the GitHub repo: https://github.com/tomXGames/SevenSegment_Display

Any help is really appreciated!

Thank you,

Self refers to the current instance of the object defined by your class.

In your class definition, I am not sure when your code that is right after the class SevenSegments: will execute. Initialization code needs to be in the __init__() routine.

You also need to be careful with variable scope. pos and self.pos are not the same thing - lines 6-9. Your code does not make clear where you expect the program to get the w and h, but perhaps that is in the class definition for Segment. It is also a really bad idea to have a variable and a function with the same name - line 5. If Segment is a class as I suspect and you are endeared to that name, use lower case for the variable. Still hard to debug.

Do you mean to have a comma at the end of line 13?

The short answer to your question I believe is that in line 18 you have self.self.pos which makes no sense.

Please always post entire, unmodified error trace. It contains information about the problem that greatly aids in our response.

where did you get the package Segment? I can't find it.

@jefsummers Thanks for your suggestions! I implemented them and it seems no I get this error:

processing.app.SketchException: IndexError: index out of range: 0

@Larz60+ Sorry for not explaining the problem well enough. I now put the entire error trace in. I took the class Segment from the Segment.py file. I updated the repository, so make sure you have the new ones.
