Question

We have a class with some mathematical functions inside

class MyObjects(object):
    q=1      #could be any number
    def f(x,y):
        return q*y+x    #could be any mathematical function

Let’s say we want to create 100 new objects named like object_1 , object_2…object_100 of this class and all of them must have a variable q defined, but defined for each object as q_1 , q_2 … q_100 but we want every time an object is created to increment the value of q like if q=1:
q_1=q+1
q_2=q_1+1 and so on. As displayed previously all objects must use the f(x,y) function of the class named for each object like f_1 , f_2 … f_100 . the number of objects generated is going to be set by the user with input() and that is the reason i would like to automate this procedure which is very cumbersome to do “by hand” by adding that is something like a hundred objects in the code. So can i automate this procedure? Python begginer, monty python veteran lol. Feel free to edit the question if you can rephrase it in a more precise manner.

Answer 1

Define a class attribute q and an instance attribue q.
And every time a new instance is created the MyObjects.q will be incremented and that incremented value will be assigned to self.q

class MyObjects(object):
    q=0
    def __init__(self):
       MyObjects.q+=1
       self.q=MyObjects.q

    def f(self,x,y):
        return self.q*y+x
inp=input("Enter number of objects: ")
dic={}
for x in range(1,inp+1):
    dic[x]=MyObjects()

output:

>>> dic[1].q
1
>>> dic[2].q
2
>>> dic[3].q
3
>>> dic[1].f(2,5)
7
>>> dic[2].f(2,5)
12
>>> dic[3].f(2,5)
