Why doesn’t the program recognize the "N"?

Question

class primao:
    from random import randrange

    def __init__(self, N=randrange(2,100), divisor=0, pontos=0, laco=True, prova_cabal= N%divisor):
        self.N= N
        self.divisor= divisor
        self.pontos= pontos
        self.laco= laco
        self.prova_cabal= prova_cabal

    def gerar_primo(self):
        for i in range(1,self.N,+1):
            self.divisor += 1                       
            if self.prova_cabal == 0:
                self.pontos += 1
            if self.pontos > 2:
                self.laco= False
        if laco == False:
            gerar_primo()   
        if pontos <= 2:
            self.laco = True
            return self.N


A= primao()
A.N_Primo()

Answer 1

The error is being generated because you did not initialize the variables N and divisor in its class or out before being used to define the parameter prova_cabal = N % divisor.

I don’t know what your goal is with this code, but if you initialize these variables, the error will be deleted. Example:

class Primao(object):
    from random import randrange

    N = 1
    divisor = 1

    def __init__(self, N = randrange(2,100), divisor=0, pontos=0, laco=True, prova_cabal = N % divisor):

        self.N = N
        self.divisor = divisor
        self.pontos = pontos
        self.laco = laco
        self.prova_cabal = prova_cabal

    # Código restante...

Other than that your code is full of error. You are calling the method N_Primo() that doesn’t exist, you forgot to use self when calling the attribute laco and the method gerar_primo, and even with these corrected details, your code still generates the following error:

Recursionerror: Maximum recursion Depth exceeded in comparison

This error is being generated because you exceed the maximum allowed calls of the same method in Python.

I suggest you review your code right, looking for typos to fix them and improve the logic of your code.
