How to pass values from a group of object attributes into tkinter combobox values

I'm looking to populate a tkinter combobox with a list of attribute values contained within a set of objects from a certain class. I have a method that works but it seems inefficient as the number of objects rises.

I've attempted using while/for statements but am perhaps failing in syntax due to the formatting for tkinter values.

class Customer:
def __init__(self, name, people):
    self.name = name
    self.people = people
customer1 = Customer(“First Customer”, [“Brian”, “Sally”])

customer2 = Customer(“Second Customer”, [“Kevin”, “James”])

customer3 = Customer(“Third Customer”, [“Peter”, “Sarah”])
customer_list = [customer1, customer2, customer3]
from tkinter import *

from tkinter.ttk import *
window = Tk()

window.title(“Command Console”)

window.geometry(‘350x200’)
l1 = Label(window, text = “Select a customer.”)

l1.grid(column=0,row=0)
b1 = Button(window, text = “Grab”)

b1.grid(column=1,row=1)
c1 = Combobox(window)

c1[‘values’] = customer_list[0].name, customer_list[1].name,

customer_list[2].name

c1.grid(column=0,row=1)

Although the above works, it would be preferred to populate the .name values for i = 0 to i < len(customer_list) or similar, however I can’t work out a mechanism.
