How to build an Email Slicer using Python

What exactly is indeed an Email Slicer?

Email Slicer is simply a program that requires an email id as input and performs slicing processes on it to return the username and domain of the email id.

As an example:

input:

buddhiict@gmail.com

Output:

Email slicer by Buddhi ashen
username stand for the Your username based on the given email address.
domain means the '@gmail.com' or '@yahoo.com' or @outlook.com' based on the given email address .
to proceed simply enter 'yes' or 'y
to exit the programme simply enter 'no' or 'n'
proceed to programme Y/N : y
<<<<<<< E-mail slicer >>>>>>>>
Want to proceed Y/N : y
Enter an email to slice : buddiict@gmail.com
--------------------------------
<-- username = buddiict -->
<-- domian = '@' gmail.com -->

<<<<<<< E-mail slicer >>>>>>>>

Here we got buddhiict as username and gmail.com as a domain.

This project is super simple and quick and it doesn't require any setup so let's quickly jump to coding and build this.

Let's Code

So this first we are going to do is to ask the user to enter the email to be sliced.

email = input("Enter Your Email: ").strip()

in here we create a variable called email. after that we get a user input by using input tag. by using strip() we can remove any additional & unwanted spacing on both sides of string.

Let's move to the next step now.

username = email[:email.index('@')]
domain = email[email.index('@') + 1:]

Here we are slicing the user input to obtain the username and domain and ignore the rest. Let's see how it works.

In case of username variable we only want to keep the part of the string which comes before @ and ignore the rest.

Here we are making use of slicing operator : and index() function. index() function searches for the particular element or character within the string and lists it is associated with and return its index number.

Let's consider the input is buddhiict@gmail.com, so when we write email[:email.index('@')]i, our index() function will interpret it as email[:13] as our @ is located at index 13. Now email[:13] knows that @ is located at index 13, so now it will keep the part before index 13 and discard the rest.

This exact same process is followed for domain also.

And now finally, let's print our output.

print(f"Your username is {username} & domain is {domain}")

We are making use of f-string, a new addition to Python 3 which allows us to directly place our variables in the output string. Feel free to make use of format() or old school + or , operators if you don't want to use f-string.
