How to Create a list of Objects in Python

John on May 13, 2021

To create a list of objects from a class in Python, define them and store them in variables by calling the class constructor. Then add the object instances as a comma-separated list inside [] (square brackets.)

class name_object(object):
   def __init__(self, name):
       self.name = name
       
object_1 =  name_object('john')
object_2 =  name_object('james')
object_3 =  name_object('jeff')


objects = [object_1, object_2, object_3]

for obj in objects:
    print(obj.name)

Add Objects to an Existing List

To add new objects to an existing list, use the list.append() function and pass the object as the first argument.

class name_object(object):
   def __init__(self, name):
       self.name = name
       
objects = []

object_1 =  name_object('john')
object_2 =  name_object('james')
object_3 =  name_object('jeff')

objects.append(object_1)
objects.append(object_2)
objects.append(object_3)

for obj in objects:
    print(obj.name)
