Python Forum

Hello, I have for files AllOnesGA.py with the main(), GeneticAlgorithm.py,Population.py and Individual.py

The cuestion is that pycharm mark as an error the overloading of the constructor
thanks

class Population:
    def __init__(self,populationSize):
        self.populationSize=individual_file[populationSize]
    def __init__(self,populationSize,chromosomeLength):
        self.population = individual_file.Individual[populationSize]
        for individualCount in range (0,populationSize):
            individual = individual_file(chromosomeLength)
            self.population[individualCount]= individual
        ...

what I'm doing wrong

ps:the error is

Error:
 File "/home/psm/PycharmProjects/AllOnesGA/genetic_algorithm.py", line 12, in initPopulation
    population = population_file.Population(self.populationSize, chromosomeLength)
  File "/home/psm/PycharmProjects/AllOnesGA/population_file.py", line 7, in __init__
    self.population = individual_file.Individual[populationSize]
TypeError: 'type' object is not subscriptable

I would say

self.population = individual_file.Individual[populationSize]

should be

self.population = individual_file.Individual(populationSize)

note brackets vs square brackets
Also note you don't need __init__() twice. The second one simply override the first one
And based on all your questions so far I would suggest to take [once again] an introductory tutorial on OOP

Hello, I correct some mistake and now I have this new error
