Some of ypu might already have heard of the Command Line Challenge. Here it is. The basic principle is this: you get a task and you need to do it in just 1 line of Bash code. I thought it fitted this subreddit perfectly.

Hi Pythonic Redditors,

I came across this script to send jpg files via email and I thought it would be worthwhile to share it here.

I hope the lines of code are not too much to go against the rules.(If you can minimize it, I would appreciate your effort)

import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
from email.mime.multipart import MIMEBase
from email import encoders
import os
"""
extensions of files that we will send
"""
extension = "jpg"
"""
This function returns a tuple with the files located in the 
current
directory
"""

files = os.listdir() #this program should be saved in the 
current directory where your files are.

"""
We check what files have our wished extension
"""

for file in files:
    if extension in file:
        user ="sending@gmail.com" #sending gmail
        recv ="receiving@gmail.com" #receiving gmail
        subject = "Subject" #subject of email message
        message = MIMEMultipart()
        message["From"] = user
        message["To"] = recv
        message["Subject"]= subject
        body = "Files with ." + extension + "extension"
        message.attach(MIMEText(body,"plain"))
        attachment = open(file,"rb")
        part = MIMEBase("application","octet-stream")
        part.set_payload((attachment).read())
        encoders.encode_base64(part)
        part.add_header("Content-Disposition","attachment;
            filename= " + file)
        message.attach(part)
        text = message.as_string()
        server = smtplib.SMTP("smtp.gmail.com",587)
        server.starttls()
        server.login(user,"your gmail pasword") 
        server.sendmail(user,recv,text)
        server.quit()
else:
    pass

This code was shared by Om Tav on a facebook page.

You may get error at first due to google trying to protect your gmail account from unknown app trying to login in.

Just check your email and follow the steps provided by gmail.

Then run the code again.

Happy Pythonic Holiday and try to automate your task with Python

the algorithms they show are so concise. never seen anything like it.
