How to get user input from tkinter with python

It's kind of an email sending app, the user writes in his email address, password and the email address of the other person where he wants to send his mail to. And the subject and the message. This is the idea.
I made a little window with tkinter and I want that if the user writes down his thinks and click the send email button its send the email. But it gives errors:

Exception in Tkinter callback
Traceback (most recent call last):
File "C:tkinter__init__.py", line 1702, in __call__return self.func(*args)

line 37, in email_send server.login(from_address, password.get())

File "C:smtplib.py", line 721, in login initial_response_ok=initial_response_ok)

File "C:smtplib.py", line 631, in auth (code, resp) = self.docmd("AUTH", mechanism + " " + response)

TypeError: must be str, not bytes


I think there is something with the way I'm getting the input

from tkinter import *
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

window = Tk()
window.title("E-mail sender")
window.geometry("300x350")

fromaddrs = StringVar()
password = StringVar()
toaddrs = StringVar()
subject = StringVar()
messagen = StringVar()

from_address = fromaddrs.get()
to_address = toaddrs.get()
msg = MIMEMultipart()
msg['From'] = from_address
msg['To'] = to_address
msg['Subject'] = subject.get()

message = messagen.get()

msg.attach(MIMEText(messagen.get(), 'plain'))

entry_from_address = Entry(window, textvariable=fromaddrs)
entry_from_password = Entry(window, textvariable=password)
entry_to_address = Entry(window, textvariable=toaddrs)
entry_subject = Entry(window, textvariable=subject)
entry_message = Entry(window, textvariable=messagen)


def email_send(event):
server = smtplib.SMTP('smtp.gmail.com', 587)
server.starttls()
server.login(from_address, password.get())
text = msg.as_string()
server.sendmail(from_address, to_address, text)
server.quit()
print("Email send!")


label_from_address = Label(window, text="Email address: ")
label_from_password = Label(window, text="Password:")
label_to_address = Label(window, text="Message to:")
label_subject = Label(window, text="Subject:")
label_message = Label(window, text="Message:")

entry_from_address.grid(row=0, column=1)
entry_from_password .grid(row=1, column=1)
entry_to_address.grid(row=2, column=1)
entry_subject.grid(row=3, column=1)
entry_message.grid(row=4, column=1)

label_from_address.grid(row=0, sticky=E)
label_from_password .grid(row=1, sticky=E)
label_to_address.grid(row=2, sticky=E)
label_subject.grid(row=3, sticky=E)
label_message.grid(row=4, sticky=E)


email_send_button = Button(window, text="Send email")
email_send_button.bind("<Button-1>", email_send)
email_send_button.grid(columnspan=2)

window.mainloop()


I hope someone can help

I made some changes in the code, now the e-mails and the password working, but the subject and the text isn't:

fromaddrs = tkinter.StringVar()
password = tkinter.StringVar()
toaddrs = tkinter.StringVar()
subject = tkinter.StringVar()
message = tkinter.StringVar()


entry_from_address = ttk.Entry(window, textvariable=fromaddrs)
entry_from_password = ttk.Entry(window, textvariable=password)
entry_to_address = ttk.Entry(window, textvariable=toaddrs)
entry_subject = ttk.Entry(window, textvariable=subject)
entry_message = ttk.Entry(window, textvariable=message)


msg = MIMEMultipart()

msg['From'] = fromaddrs.get()
msg['To'] = toaddrs.get()
msg['Subject'] = subject.get()

msg.attach(MIMEText(message.get(), 'plain'))


def email_send(*args):

server = smtplib.SMTP('smtp.gmail.com', 587)
server.starttls()
server.login(fromaddrs.get(), password.get())
server.sendmail(fromaddrs.get(), toaddrs.get(), msg.as_string())
server.quit()
print("The message send!")


send_button = tkinter.Button(window, text="Send e-mail", command=email_send)
send_button.grid(columnspan=2)


from_address = fromaddrs.get()

To be honest I don't know if there is a direct solution to your problem. This is simply one of the pitfalls of tkinter. I have spent some time trying to develop my own custom tkinter widgets that rely on the basic bind function. This way, instead of using the preinstalled entry widget, I simply bind a keyboard event to a particular label, and as I type the text of this label changes. Once I want to collect/store the text that I entered, I would simply use the cget('text') for my label. Sadly, I have not really gotten to making the code library for such an entry widget. I have however previously written some raw code for such entry widgets so I know they will work.

bind

cget('text')
