Get the value of an entry created with a button

Question

I am new to python tkinter.I would like to get some help from you. After adding a few entries with the button (Add_button), then entering a value to each of them, I would like to know how I can get the value from those entries and add them up. I tried a few things, they did not work.

from tkinter import *

root=Tk()


s=0
def add_button():
    global s
    s +=1
    for i in range(s):
        lab1=Label(root, text='lab1')
        lab1.grid(row=i, column=1)
        entry1=Entry(root)
        entry1.grid(row=i, column=2)
        
        

bouton_add=Button(root, text='Create widget', command=add_button )
bouton_add.grid(row=5, column=0)

root.mainloop()

from tkinter import *

root=Tk()

a=[]
s=0
def add_button():
    global s
    s +=1
    lab1=Label(root, text=f'lab{s}')
    lab1.grid(row=s, column=0)
    entry1=Entry(root)
    a.append(entry1)
    entry1.grid(row=s, column=1)
        
def get_entry():
    a_data=[]
    for i in a:

        a_data.append(i.get())
    print(a_data)

bouton_add=Button(root, text='Create widget', command=add_button )
bouton_add.grid(row=5, column=0)


bouton_add=Button(root, text='get', command=get_entry )
bouton_add.grid(row=5, column=1)
root.mainloop()

The for-loop with range(s) would create a new entry over the previous entry, so even if you use the get_entry method, you will get result on previous entry as '' only.

I have just stored references to the entry when they are create in a list, and to get their value, used a for loop for elements in the list a, and used .get method to get thier value.
