CANT GET VALUE FROM ENTRY - python-3.x

Question

I'm attempting to develop a registration form, but I can't get the value of the entries because nonetype and return self func are specified.
I tried entering values into the entries, but nothing worked. Again, we find that understanding some of the features and structure of your code is required before you can make modifications.
import tkinter as tk
from tkinter import *
from tkinter import ttk
class App():
# created window
# made all entries global
##################################################### ENTRIES #####################################################################
# some entries
def submit():
MsgBox = messagebox.askokcancel('FYEF',"stuff",icon = 'info')
if MsgBox == True:
# ENTRIES
enroll = enroll_code.get()
readonly = readonly_combo.get()
school = schools.get()
sc_did = sc_id.get()
sc_dd = sc_add.get()
vr = vrb.get()
if vr == 1:
vr = 'Private'
elif vrb == 2:
vr = 'Public'
PSA = PSA_no.get()
lr_no = lr_number.get()
last_nme = last_name.get()
first_nme = first_name.get()
mid_nme = mid_name.get()
ext_nme = ext_name.get()
birth_dte = birth_date.get()
ageyr = age.get()
vhr = vhar.get()
if vhr == 1:
vhr = 'Male'
elif vhr == 2:
vhr = 'Female'
iic = ip_ic.get()
if iic == 1:
iic = 'Yes'
elif iic == 2:
iic = 'No'
mother_ton = mother_tongue.get()
relgaff = relg_aff.get()
spneeds = sp_needs.get()
eadd = em_add.get()
hom_add = home_add.get()
f_name = fath_name.get()
f_contact = fath_contact.get()
m_name = moth_name.get()
m_contact = moth_contact.get()
g_name = guar_name.get()
g_contact = guar_contact.get()
m_wifi = means_wifi.get()
p_modal = pref_modal.get()
concern = concerns.get()
approve = approval.get()
tday = date.today()
dte = today.strftime("%B %d, %Y")
woot = tk.Tk()
wlc = ttk.Label(woot, text='🎊Welcome!', font='bold, 30').place(x=50,y=100)
# SUBMIT Button
submit_button = ttk.Button(tab_2, text="Submit", command=submit).place(x=655,y=700)
App()

Answer 1

Edit: Asked by Delrius Euphoria. The woot = tk.Tk(), app = App(), and woot.mainloop() should be outside of class . ttk.Label should be outside of function
Try this:
import tkinter as tk
from tkinter import *
from tkinter import ttk
woot = tk.Tk()
class App():
# created window
# made all entries global
##################################################### ENTRIES #####################################################################
# some entries
def submit():
MsgBox = messagebox.askokcancel('FYEF',"stuff",icon = 'info')
if MsgBox == True:
# ENTRIES
enroll = enroll_code.get()
readonly = readonly_combo.get()
school = schools.get()
sc_did = sc_id.get()
sc_dd = sc_add.get()
vr = vrb.get()
if vr == 1:
vr = 'Private'
elif vrb == 2:
vr = 'Public'
PSA = PSA_no.get()
lr_no = lr_number.get()
last_nme = last_name.get()
first_nme = first_name.get()
mid_nme = mid_name.get()
ext_nme = ext_name.get()
birth_dte = birth_date.get()
ageyr = age.get()
vhr = vhar.get()
if vhr == 1:
vhr = 'Male'
elif vhr == 2:
vhr = 'Female'
iic = ip_ic.get()
if iic == 1:
iic = 'Yes'
elif iic == 2:
iic = 'No'
mother_ton = mother_tongue.get()
relgaff = relg_aff.get()
spneeds = sp_needs.get()
eadd = em_add.get()
hom_add = home_add.get()
f_name = fath_name.get()
f_contact = fath_contact.get()
m_name = moth_name.get()
m_contact = moth_contact.get()
g_name = guar_name.get()
g_contact = guar_contact.get()
m_wifi = means_wifi.get()
p_modal = pref_modal.get()
concern = concerns.get()
approve = approval.get()
tday = date.today()
dte = today.strftime("%B %d, %Y")
wlc = ttk.Label(woot, text='🎊Welcome!', font='bold, 30').place(x=50,y=100)
enroll_code =ttk.Entry(woot).place(x=50,y=150)
# SUBMIT Button
submit_button = ttk.Button(woot, text="Submit", command=submit).place(x=655,y=700)
app = App()
woot.mainloop()
