python program to rename the file with current date in MMDDYYY format and send email with attachment -


this question has answer here:

below program send email attachment:

i want rename file student.xlsx student_mmddyyyy.xlsx , send email renamed file , after email sent want delete file. how can that?

here code: 

import smtplib email.mime.multipart import mimemultipart email.mime.text import mimetext email.mime.base import mimebase email import encoders fromaddr = "myemailid" toaddr = "toaddress"  msg = mimemultipart() msg['from'] = fromaddr msg['to'] = toaddr msg['subject'] = "please find attachment" body = "hi"  msg.attach(mimetext(body, 'plain'))  filename = "student.xlsx" dt = str(datetime.datetime.now()) attachment = open("c:\\users\\prashanth\\desktop\\student.xlsx", "rb") part = mimebase('application', 'octet-stream') part.set_payload((attachment).read()) encoders.encode_base64(part) part.add_header('content-disposition', "attachment; filename= %s" % filename)  msg.attach(part)  server = smtplib.smtp('smtp.gmail.com', 587) server.starttls() server.login(fromaddr, "password") text = msg.as_string() server.sendmail(fromaddr, toaddr, text) server.quit()

you can use os.rename() rename file, , os.remove() remove file. , desired date format can use strftime(), example:

import os datetime import datetime date_now = datetime.now().strftime('%m%d%y') file_one = "c:\\users\\prashanth\\desktop\\student.xlsx" file_two = 'c:\\users\\prashanth\\desktop\\student_{}.xlsx'.format(date_now) os.rename(file_one, file_two) # send email , attach file # , once you're done: os.remove(file_two)

edit:

you need close() file before renaming or removing it, or better yet use with-statement open file , auto close when you're done, example:

attachment = open(file, "rb") part = mimebase('application', 'octet-stream') part.set_payload((attachment).read()) attachment.close()

or

with open(file, "rb") attachment:     part = mimebase('application', 'octet-stream')     part.set_payload((attachment).read())

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
