How to create multiple class objects with a loop in python

Question

Suppose you have to create 10 class objects in python  and do something with them  like   obj 1   MyClass   other object add obj 1  obj 2   MyClass   other object add obj 2        obj 10   MyClass   other object add obj 10    How would you do it with a loop  and assign a variable to each object  like obj 1   so that the code will be shorter  Each object should be accessible outside the loop  obj 1 do sth

Using a dictionary for unique names without a name list:

class MyClass:
    def __init__(self, name):
        self.name = name
        self.pretty_print_name()

    def pretty_print_name(self):
    print("This object's name is {}.".format(self.name))

my_objects = {}
for i in range(1,11):
    name = 'obj_{}'.format(i)
    my_objects[name] = my_objects.get(name, MyClass(name = name))

Output:

"This object's name is obj_1."
"This object's name is obj_2."
"This object's name is obj_3."
"This object's name is obj_4."
"This object's name is obj_5."
"This object's name is obj_6."
"This object's name is obj_7."
"This object's name is obj_8."
"This object's name is obj_9."
"This object's name is obj_10."

Creating a dictionary as it has mentioned  but in this case each key has the name of the object name that you want to create  Then the value is set as the class you want to instantiate  see for example   class MyClass     def   init   self  name          self name   name        self checkme    awesome     format self name       instanceNames     red    green    blue      Here you use the dictionary holder    name  MyClass name name  for name in instanceNames    Then you just call the holder key and you will have all the properties and methods of your class available for you   holder  red   checkme   output    awesome red
