Python http_head method

Seeing as there is no really easy way to do a HTTP HEAD request from python, I wrote up the following small method:

In advance I’d like to apologize for the method that assemblies the request path.

Update: Added handling of redirects.

def http_head(url):
    import httplib
    import urlparse
 
    redirects = 0
 
    while redirects < 10:
        scheme, netloc, path, query, fragment = urlparse.urlsplit(url)
 
        if scheme == 'https':
            conn = httplib.HTTPSConnection(netloc)
        else:
            conn = httplib.HTTPConnection(netloc)
 
        conn.request("HEAD", "%s%s%s%s%s" % (path, query and "?" or "", query,
                                             fragment and "#" or "", fragment))
 
        res = conn.getresponse()
 
        if res.status in (301, 302) and res.getheader('location'):
            url = res.getheader('location')
            redirects += 1
        else:
            break
 
    return res.status, res.reason

Very simple email sending method in python

I needed to send an email, so I came up with this:

 
def send_plain_mail(subject, body, from_mail, to):
    import smtplib
    from email.MIMEText import MIMEText
    from email.Encoders import encode_quopri
 
    msg = MIMEText(body, 'plain', 'iso-8859-1')
 
    msg['Subject'] = subject
    msg['From'] = from_mail
    msg['To'] = to
 
    s = smtplib.SMTP()
    s.connect()
    s.sendmail(from_mail, [to], msg.as_string())
    s.close()

Not rocket science, but it gets the job done.
