List of Objects print <__main. Problem

[Kol789]

Hello buran,

this is acutally my code:

class Chromosom(object):                          #Chromosom wird erstellt mit Fitness,Index, Chromosom  
   
  def __init__(self, fitness, index, chromosom):
    self.fitness=fitness
    self.index=index
    self.chromosom= chromosom
     
  def myfunc(self):                               # Printe ein Chromosom
    print(self.fitness,self.index,self.chromosom )
 
  def __repr__(self, fitness, index, chromosom):
    return "<a:%s, b:%s, c:%s, d:%s>" % (self.fitness, self.index, self.chromosom)
 
class LKW(object):                                # Erzeuge LKW mit Uhrzeit
 
  def __init__(self, uhrzeit):
    self.uhrzeit=uhrzeit
 
  def __str__(self):
    return "<Test a:%s>" % (self.uhrzeit)
 
population=[]
  
p1= Chromosom(1,5,[123456])
print(p1)
 
p2=LKW(12)
print(p2)
 
 
population.append(p1)
population.append(p2)
 
print(population)

But when i print the population i get an error __repr__ missing 3 required positional arguments in line 25 print(p1)
What am i doing wrong?
