Creating a list of object in Pyton

[stevencorrea]

I have created a basic class and each new object that I create, I want to append it to a list. When I print the length of the list, the output is 1, not 3. Based on the output generated within the for loop, I am generating 3 different objects. Any clues as to why the listOfObjects has length 1?

class newObject (object):
    total = 0


    @staticmethod
    def status():
        print("\nThe total number of new objects is", newObject.total)


    def __init__(self, name):
        print("A new object has been created!")
        self.name = name
        newObject.total += 1


#main
print("Accessing the class attribute newObject.total:", end=" ")
print(newObject.total)


print("\nCreating objects!")


for i in range(3):
    listOfObjects = []
    listOfObjects.append(newObject("object"+str(i+1)))
    newObject.status()

print (len(listOfObjects))

Welcome to the forums. It would help greatly if you could use code tags when posting python code in order to preserve indentation.

Your problem is that this line:

  listOfObjects = []

is inside the for loop. So on each pass through the loop you empty out the list and append 1 item. The above line should instead appear before the for loop, like this:

class newObject (object):
  total = 0


  @staticmethod
  def status():
    print("\nThe total number of new objects is", newObject.total)


  def __init__(self, name):
    print("A new object has been created!")
    self.name = name
    newObject.total += 1


#main
print("Accessing the class attribute newObject.total:", end=" ")
print(newObject.total)


print("\nCreating objects!")


listOfObjects = []
for i in range(3):
  listOfObjects.append(newObject("object"+str(i+1)))
  newObject.status()

print (len(listOfObjects))
