Coding Challenge 1: Email Usernames
PYTHON*********************************************************
In this coding challenge, you will be retrieving email usernames
from a string. You will write a function named get_usernames() that
takes in a string as it's input parameter, and returns a list of
email usernames in the string. The input
strings will contain 0 or more emails in the format
username@domainname, and the '@' symbol will only appear in the
context of an email. The order of usernames should match the order
in the input text.
For example:
EXAMPLE 1 text: "If you need help on an
assignment, email [email protected] or [email protected]" return:
['help', 'support']
EXAMPLE 2 text: "Good morning! I hope
you're having a great time with CSE 8A!" return: []
EXAMPLE 3 text: "I've been having a lot of
trouble reaching you, can you please email me at [email protected]?
Again, my email is [email protected]!" return: ['cse', 'cse']
Here is the problem description:
Function Name: get_usernames
Parameter: text - A string corresponding to a
piece of text containing 0 or more emails.
Return: A list of the email usernames in the
input text.
Description: Given a piece of text, extract
all email usernames and return them in a list.
