Sending Email At the End of Your Process

Here is a nice script that will allow you to send emails at the end of your python script, or where ever you want to.  Today I just posted a comment on my topic of long running scripts, and I am adding this component onto my workflow, so I know when processes finish or that they have completed.

Enjoy

import arcpy
import smtplib
import os
from email.MIMEMultipart import MIMEMultipart
from email.MIMEBase import MIMEBase
from email.MIMEText import MIMEText
from email.Utils import COMMASPACE, formatdate
from email import Encoders
def send_mail(send_from, send_to,
              subject, text,
              f="",server="THE SERVER URL"):
    assert type(send_to)==list
    # Provide the name of your email server below
    #
    msg = MIMEMultipart()
    msg['From'] = send_from
    msg['To'] = COMMASPACE.join(send_to)
    msg['Date'] = formatdate(localtime=True)
    msg['Subject'] = subject
 
    msg.attach( MIMEText(text) )
    if os.path.isfile(f):
        part = MIMEBase('application', "zip")
        part.set_payload( open(f,"rb").read() )
        Encoders.encode_base64(part)
        part.add_header('Content-Disposition', 'attachment; filename="%s"' % os.path.basename(f))
        msg.attach(part)
    smtp = smtplib.SMTP(server)
    smtp.sendmail(send_from, send_to, msg.as_string())
    smtp.quit()
def trace():
    import traceback
    import inspect
    import sys
    '''
    trace finds the line, the filename and error message and returns it
    to the user
    '''
    tb = sys.exc_info()[2]
    tbinfo = traceback.format_tb(tb)[0]
    # script name + line number
    line = tbinfo.split(", ")[1]
    filename = inspect.getfile( inspect.currentframe() )
    # Get Python syntax error
    #
    synerror = traceback.format_exc().splitlines()[-1]
    return line, filename, synerror  
def main(*argv):
    try:
        #    User Inputs
        #
        server = argv[0]
        subject = argv[1]
        message = argv[2]
        recievers = str(argv[3]).split(';')
        #    Email Function
        #
        send_mail(
              "NOTIFICATION@DONOTREPLY.COM",
              recievers,
              subject,
              message,
              "",
              server)
        arcpy.SetParameterAsText(4,True)
    except:
        arcpy.AddError(arcpy.GetMessages(2))
        arcpy.AddError(str(trace()))
        arcpy.SetParameterAsText(4,False)
if __name__ == "__main__":
    argv = tuple(arcpy.GetParameterAsText(i)
            for i in range(arcpy.GetArgumentCount()))
    main(*argv)


Clean Up Files - A Helpful Function

I've been developing window services using python (win32api), and often I find is necessary that I need to clean up files at the end of the process.  I developed a small function that is quite helpful for cleaning up files by extension:

def cleanUpFiles(directory,extension):
    dir = directory
    files = os.listdir(dir)
    for f in files:
      if not os.path.isdir(f) and extension in f:
        os.remove(dir + os.sep + f)

Python Tip: Format number with comma

Here is a good little tip for the client that wants to see those commas in there numbers: (for python 2.6)

>>> import locale
>>> locale.setlocale(locale.LC_ALL,"")
'English_United States.1252'
>>> y = locale.format('%d',1239811,True)
>>> print y
1,239,811

Killing Python.exe Processes Fast and Easy

When performing multiprocessing or subprocessing, sometimes you need to kill that script, and fast.  You can use task manager to do this, but that's too many clicks.

There is a great window's program called taskkill.exe.  To do this process, you need to create a link.  Once you have the link, enter in the following command: 'C:\Windows\System32\taskkill.exe /F /IM python.exe /T'

All processes will end quickly.
