By reading this article, you’ll learn the basic steps required to send a simple email in Python. We’ll be using a built-in module called
smtplib. This means there will be no additional setup or installation required. Based on the official documentation, this module:
There are three sections in this tutorial
Let’s proceed to the next section to set up the Flask server.
It’s highly recommended to set up a virtual environment before you proceed. Activate your virtual environment, and install Flask via the following code:
pip install flask
Create a Python file, and add in the following code to create a simple server. I will be naming it
from flask import Flask, request, jsonify app = Flask(__name__) @app.route('/') def hello_world(): return "Hello world!" if __name__ == "__main__": app.run('0.0.0.0',port=5000)
Save the file, and run it with the following code. Replace the name of the file accordingly. I’m using
test.py for this tutorial.
Open up a browser, and access it based on the IP of your machine. You can open up a command line and type
ipconfig to identify the address of your machine. You should be able to see the following output.
Proceed to the next section, and start playing around with the
First and foremost, add the following import declaration on top of the Python file.
import smtplib from email.mime.multipart import MIMEMultipart from email.mime.text import MIMEText from email.mime.image import MIMEImage
email.mime module is required to craft the email messages. It’s part of the legacy module that’s still quite useful. Feel free to use other modules if you intend to create complex email messages.
The SMTP objects accept two input parameters:
Please be noted that I’m using Outlook as the SMTP server, and the connection is based on TLS. In fact, you can use your own SMTP server or third-party services such as Gmail or Outlook. You have to modify the parameters based on the setting of the SMTP server you’re going to use. You have to allow your email to be accessible by third-party services. The setting for Outlook is as follows. Modify them accordingly if you’re using another SMTP server.
SMTP object with the following code. Replace
smtp.office365.com with the server name of your SMTP server.
smtpObj = smtplib.SMTP('smtp.office365.com', 587)
Continue by appending the following code to start the authentication:
smtpObj.ehlo() smtpObj.starttls() smtpObj.login("email@example.com", "password")
The next step is to create the email messages. Let’s create a function called
send_test_mail and define the sender and receiver emails. You can use your own email as both the sender and receiver to test it out. I’ve added an additional string input called
body. It’ll be the main content that we’ll be sending over in the email.
def send_test_mail(body): sender_email = "firstname.lastname@example.org" receiver_email = "email@example.com"
Inside the function, create a
MIMEMultipart object that’ll be responsible for storing all the
msg = MIMEMultipart() msg['Subject'] = '[Email Test]' msg['From'] = sender_email msg['To'] = receiver_email
Next, create the
MIMEText object using the input parameter we defined earlier. We’ll format it inside an HTML string. Attach it to the
msgText = MIMEText('<b>%s</b>' % (body), 'html') msg.attach(msgText)
The last step is to call the
sendemail function. It’s recommended to wrap it inside a
try catch block.
try: smtpObj.sendmail(sender_email, receiver_email, msg.as_string()) except Exception as e: print(e)
In order to test it, you need to make a call to the
send_test_mail function. The easiest way is to do it inside the main function. Feel free to change the input text.
if __name__ == "__main__": send_test_mail("Welcome to Medium!") app.run('0.0.0.0',port=5000)
Run the server, and you should see the following email inside your mailbox.
You can easily add an attachment such as a CSV or TXT file to the email message via the following code. Simply assign the proper path, and open it inside a
filename = "example.txt" msg.attach(MIMEText(open(filename).read()))
You should be able to get the following result.
For image attachments, you have to use the
MIMEImage object instead. You can change the name of the attachment by adding a header
Content-Disposition to it.
with open('example.jpg', 'rb') as fp: img = MIMEImage(fp.read()) img.add_header('Content-Disposition', 'attachment', filename="example.jpg") msg.attach(img)
You should get the following result once you run the server.
Feel free to check out the complete code in the following link.
from flask import Flask, request, jsonify import smtplib from email.mime.multipart import MIMEMultipart from email.mime.text import MIMEText from email.mime.image import MIMEImage smtpObj = smtplib.SMTP('smtp.office365.com', 587) smtpObj.ehlo() smtpObj.starttls() smtpObj.login("firstname.lastname@example.org", "password") app = Flask(__name__) def send_test_mail(body): sender_email = "email@example.com" receiver_email = "firstname.lastname@example.org" msg = MIMEMultipart() msg['Subject'] = '[Email Test]' msg['From'] = sender_email msg['To'] = receiver_email msgText = MIMEText('<b>%s</b>' % (body), 'html') msg.attach(msgText) filename = "example.txt" msg.attach(MIMEText(open(filename).read())) with open('example.jpg', 'rb') as fp: img = MIMEImage(fp.read()) img.add_header('Content-Disposition', 'attachment', filename="example.jpg") msg.attach(img) try: smtpObj.sendmail(sender_email, receiver_email, msg.as_string()) except Exception as e: print(e) @app.route('/') def hello_world(): return "Hello world!" if __name__ == "__main__": send_test_mail("Welcome to Medium!") app.run('0.0.0.0',port=5000)
Let’s recap what we’ve learned today. We started off with a simple installation of a Flask server.
Then, we proceed with initializing the
SMTP object, which is responsible for authentication and allows us to log into our own email.
After that, we crafted the email messages using
MIMEImage. This allows us to send attachments in the form of text files and images.

Welcome to my Blog, In this article, we will learn python lambda function, Map function, and filter function.
Lambda function in python: Lambda is a one line anonymous function and lambda takes any number of arguments but can only have one expression and python lambda syntax is
Syntax: x = lambda arguments : expression
Now i will show you some python lambda function examples:

You cannot imagine how easy and simple it is to configure your email account to be able to send emails to one or several contacts directly from your Python environment without any effort or complicated code.
In this article, I will walk you through the process. All you need is a Gmail account and your Python running and ready to go. Let me show you how it’s done.

Magic Methods are the special methods which gives us the ability to access built in syntactical features such as ‘<’, ‘>’, ‘==’, ‘+’ etc…
You must have worked with such methods without knowing them to be as magic methods. Magic methods can be identified with their names which start with __ and ends with __ like init, call, str etc. These methods are also called Dunder Methods, because of their name starting and ending with Double Underscore (Dunder).
Now there are a number of such special methods, which you might have come across too, in Python. We will just be taking an example of a few of them to understand how they work and how we can use them.
class AnyClass: def __init__(): print("Init called on its own") obj = AnyClass()
The first example is _init, _and as the name suggests, it is used for initializing objects. Init method is called on its own, ie. whenever an object is created for the class, the init method is called on its own.
The output of the above code will be given below. Note how we did not call the init method and it got invoked as we created an object for class AnyClass.
Init called on its own
Let’s move to some other example, add gives us the ability to access the built in syntax feature of the character +. Let’s see how,
class AnyClass: def __init__(self, var): self.some_var = var def __add__(self, other_obj): print("Calling the add method") return self.some_var + other_obj.some_var obj1 = AnyClass(5) obj2 = AnyClass(6) obj1 + obj2
