How to trigger a run button based on all the values in a list?

I have a Tkinter app and inside that app I have an OptionMenu which is giving me all the id's that are located in the list vehicleid. Please note that this list can become bigger or smaller.

Now I want my button to send the data of owner and vehicleid to a database based on what the user selects. So if I have for example 2 vehicleid's, I first need to select a specific vehicleid and for every vehicleid I need to select a specific owner.

So in case of 2 vehicleid my database should look like this:

vehicleid        owner
C161      ---    Spain
C162      ---    United Kingdom

App looks like this:

This is my code:

owner = ['Spain', 'United Kingdom', 'Malaysia']
vehicleid = ['C161', 'C162']

window = Tk()
window.title("Running Python Script") # Create window
window.geometry('550x300') # Geo of the window

##These are the option menus
dd_owner = StringVar(window)
dd_owner.set(owner[0]) # the first value
w = OptionMenu(window, dd_owner, *owner)
w.grid(row=1, column=1)

dd_id = StringVar(window)
dd_id.set(vehicleid[0])
w0 = OptionMenu(window, dd_id, *vehicleid)
w0.grid(row=0, column=1)

##The run button 
run_list_button =Button(window, text="Send data of ID's to database!")
run_list_button.grid(column=0, row=3)

##These are the titles
l1 = Label(window, text='Select Owner', width=15)
l1.grid(row=1, column=0)

l0 = Label(window, text='Select vehicle id:', width = 30)
l0.grid(row=0, column=0)

mainloop()

To begin with, you should store the data somewhere(a dictionary or a file..) and then read the data when the user presses the button.

import mysql.connector as mysql
....

mydb = mysql.connect(host = 'localhost',user = 'root',passwd = '****.',database = 'table_data')

data = {}
def store():
    if dd_id.get() not in data:
        data[dd_id.get()] = dd_owner.get()
    print(data)

def upload():
    cur = mydb.cursor()
    for item in data.items():
        sql = 'INSERT INTO table_data VALUES (%s,%s)'
        params = (item[0],item[1])

        cur.execute(sql,params)
        mydb.commit()
    
    print('Done')

....
# The store button
Button(window, text="Store data!",command=store).grid(column=0, row=3)

# The database button
Button(window, text="Send to database",command=upload).grid(column=0, row=4)

This will store the data in the database when the respective buttons are clicked, also duplicate entries or updatiion of entries will not be allowed.
