[Tutor] new line to list of strings send by email
Hello list,
I have a function which receives a string and sends it as a body of an
email.
It is a part of a program which does certain checks on network
infrastructure. When a check fails I append error message to a
error_collector list:
if self.check_axfr_refused(ip):
error_collector.append('%s:%s AXFR test for %s FAILED' %
(ns, ip, self.domainname))
At the end I send the alert like this:
if len(error_collector) != 0:
email_body = str(error_collector)
email_alert(email_body)
The problem is the resulted email (expectedly) has the alert message as one
long string.
['pdns6.ultradns.co.uk.:204.74.115.1 AXFR test for amazon.com FAILED',
'pdns6.ultradns.co.uk.:2610:a1:1017::1 AXFR test for amazon.com FAILED',
'ns4.p31.dynect.net.:204.13.251.31 AXFR test for amazon.com FAILED',...]
I tried adding '\n' to end of each string error_collector collects, but
then these were simply added to the resulted email.
What I want to achieve is that each collected error is shown on a separate
line in the email. Any advice will be well appreciated.
Here is the email sending function if in interest:
def email_alert(message, recipient=DEFAULT_RECIPIENT, subject_prefix=''):
''' Send email alert. '''
# check if we are running in quiet mode
if QUIET.lower() == 'yes':
return
msg = MIMEText(message)
msg['From'] = SENDER
msg['To'] = recipient
msg['Subject'] = subject_prefix + SUBJECT
s = smtplib.SMTP(SMTP_SERVER)
s.send_message(msg)
s.quit()

You should have the print function indented, usually by 4 spaces. This is
how Python knows which commands to be executed as part of the if block. So
this is what you'll make your code work:
>>> the_world_is_flat = True
>>> if the_world_is_flat:
... print("Be careful not to fall off!")
...
Be careful not to fall off!
The interpreter also tries to help you, it puts ... at the begging of the
line (instead of >>>) which means it expect some indentation.

Re: [Tutor] beginning encryption
if char != alphabet: should be if char not in alphabet: Otherwise you are comparing char with alphabet. What you want to do if to check if char is in alphabet.
