您必须将变量服务器声明为全局变量

global server
server = smtplib.SMTP(vari1.get(), 587)

此外，您必须更正函数，还必须连接数据。如果你这样做 a, b 你正在创建一个元组：(a, b) 而不是所需的字符串

def th():
    contents = text.get("1.0", END)
    subject = assa.get()
    message = "Subject: {}\n\n{}".format(subject, contents)
    server.sendmail(vari2.get(), toaddrs12.get(), message)
    server.quit()

    def __init__(self, master, **kwargs):
        self.master = master

        self._geom = '200x200+0+0'
        master.geometry("{0}x{1}+0+0".format(
            master.winfo_screenwidth() - pad, master.winfo_screenheight() - pad))
        master.bind('<Escape>', self.toggle_geom)

    def toggle_geom(self, event):
        geom = self.master.winfo_geometry()
        print(geom, self._geom)
