I want to create a treeview with input multiple data and then insert the multiple data to mysql

please help me......i am newbie in python programming i want to create a treeview  i want to input a multiple item to a treeview before inserting it to mysql database.This is my code....when i inserted the data to mysql....it only allow 1 item inserted and that item is the last row i inserted even do it is multiple data.

What I have tried:

def Addmultipledata():

global data_list1, data_list2,record,data
global count



global count,

first1 = fn_entry1.get()
last1 = ln_entry1.get()
ID1 = ID_entry1.get()
Address1 = Address_entry1.get()
city1 = City_entry1.get()
Zipcode1 = Zipcode_entry1.get()


data_list= [ ]
data_list.clear()
data_list.append(first1)
data_list.append(last1)
data_list.append(ID1)
data_list.append(Address1)
data_list.append(city1)
data_list.append(Zipcode1)

data_list2 = []
data_list2.append(data_list)
data_list1=tuple(data_list1)

for x in data_list2:
    six_tree.insert(parent='', index='end',iid=count,text="", values=(x[0],x[1],x[2],x[3],x[4],x[5]))
    count = count + 1

fn_entry1.delete(0, END)
ln_entry1.delete(0, END)
ID_entry.delete(0, END)
Address_entry1.delete(0, END)
City_entry1.delete(0, END)
Zipcode_entry1.delete(0, END)

def multiplesql():

    mydb = mysql.connector.connect(
    host="localhost",
    user="root",
    password="12345",
    database="SCHOOLREG"
)

my_cursor = mydb.cursor()
sql_command = """INSERT INTO Studentreg(First_Name,Last_Name,Student_id, Address,CITY,Zipcode) VALUES(%s,%s,%s,%s,%s,%s) """
# values = (record[0], record[1], record[3], record[4], record[5])
results = my_cursor.executemany(sql_command, data_list2)

mydb.commit()
