Python sends an email with the content of the entire folder as an attachment

This article describes how to send an email with the content of the entire folder as an attachment in Python. in normal cases, attachments in free mail of the carrier can only be sent to files but not folders, this script can be used to send folders (strong in hand programming: D). because I often need to back up the content in the folder to the email, it is too troublesome to upload and send files. In fact, each file sent is fixed, but the Mail title is different, therefore, python is used to write a small tool for sending files to the mailbox, execute this script in any directory, and specify the Mail mark, send the files in the specified folder to the mailbox for backup.

Installation:

Configure the recipient, Sender, smtp address, user name, password, and path of the file to be sent.

Save the file as send_files and save it to/usr/bin.

Then, set the file permission to executable:

$ chmod +x send_files

Usage:

$ Send_files 'email title'

It also has a progress bar ~~
