I want to send an email using python. The contents of the message is from a sql querry placed inside a ttk treeview widget. so how do i select and send the selected items? the code below prints (I001) inside the email.

 # Specifying the from and to addresses

        self.fromaddr = 'remlaproductions@gmail.com'
        self.toaddrs  = 'draedarockstar@gmail.com'
        self.subject = 'EMP Info'

        # Writing the message (this message will appear in the email)



        self.msg =" %s "%(self.tree.selection())


        # Gmail Login
        self.username = 'remlaproductions'
        self.password = 'draedarockstar'


        #Sending Email


        try:
            self.server = smtplib.SMTP('smtp.gmail.com',587)
            self.server.ehlo()
            self.server.starttls()
            self.server.ehlo()
            self.server.login(self.username,self.password)        
            self.server.sendmail(self.fromaddr, self.toaddrs, self.msg)
            messagebox.showinfo(title = "Email Update", message = "Email Sent")
            print(self.tree.selection())
        except:
            messagebox.showinfo(title = "Email Update", message = "Error sending email")
        self.server.quit()

thanks in advance for your help

I figured it out. Here is what i have done. tree.get_children gives you the row id what i did was get the row id from a loop, then use the id withing tree.set(id) to get a dictionary of the values. and format the output from there. Here is the code:

 self.list = " "

        self.info = self.tree.get_children()
        for i in self.info:
            self.info2 = self.tree.set(i)
            for a in self.info2:
                print(a,":",self.info2[a])
                self.list=self.list + a +": "+ self.info2[a]+'\n'

        self.msg ="{} \n" .format(self.list)

The empty string is for emailing purposes. I wanted to send an email of the result without sending the dictionary parenthesis and so forth. This is just a possible solution.

Here is one example that might help ...

I got a chance to play around with your code thank you for sharing really helped my understanding of the treeview widget
