Simple e-mail sender, that automatically changes subject for every e-mail - joker - Aug-24-2017

Hello! I am new to python. I found this code, and it works good, but I want to make a small change - I want that when I input subject, it automatically adds number 1 in the end of the subject, and for every new e-mail send, increments added number by value of one. I tried everything I can find, but it always crashes. Sad

May be someone can pinpoint the right approach? Smile

For example, if I enter in subject line "Test", and set amount to 3 e-mails, it should send 3 e-mails with subjects:
Test 1
Test 2
Test 3

The code I have so far.

print("Loading...")
from time import strftime, localtime, sleep
import os
import smtplib
def senda(msg, subject, to, amount, frm, password):
    import time
    import sys
    import smtplib
    num = 0
    left = amount
    server = smtplib.SMTP('smtp.gmail.com', 587)
    server.starttls()
    global successful
    successful = 0
    body = 'Subject: %s\n%s' % (subject, msg)
    try:
        server.login(frm, password)
    except:
        from time import sleep
        print("Error logging in.")
        sleep(5)
        import sys
        sys.exit()
    else:
        for i in range(amount):
            try:
                server.sendmail(frm, [to], body)
            except:
                pass
            else:
                successful += 1
                print("%d emails sent" % successful)

while True:
    time = strftime("%Y-%m-%d %H:%M:%S", localtime())
    user_email = input("Email: ")
    user_pass = input("Password: ")
    to = input("To: ")
    subject = input("Subject: ")
    message = '\n' + input("Message: ")
    while True:
        amt = input("Amount: ")
        try:
            amt = int(amt)
        except:
            pass
        else:
            break
    senda(message, subject, to, amt, user_email, user_pass)

For all the answers, thanks in advance! :)

Move line 15 body = 'Subject: %s\n%s' % (subject, msg) under line 26. Change it to looks like this:

        for i in range(1, amount):
            try:
                subject = "test {}".format(str(i))
                body = 'Subject: %s\n%s' % (subject, msg)
                server.sendmail(frm, [to], body)
            except:
                pass
            else:
                successful += 1
                print("%d emails sent" % successful)
