How to create a variable whose name is a function call?

Question

I'm writing a program using tkinter where an instance of the class Myclass is created every time the button create is pressed. I have a problem where I want the name of each instance to be whatever is in an entry at any given moment. For example

import tkinter

def create():
     entry.get() = Myclass(objects)

class Myclass:
    def __init__(self, objects)

entry = tkinter.Entry()

create_button = tkinter.Button(text="Create", command=create)

My issue is that I obviously can't assign a function call to another function call, so entry.get() = Myclass(objects) creates an exception. Is there a way for me to create a variable whose name is entry.get() ?
