Hide Email Address

2022-07-18.py

question = """

Given a string that has a valid email address, write a function to hide 
the first part of the email (before the @ sign), minus the first and last 
character. For extra credit, add a flag to hide the second part after the 
@ sign to your function excluding the first character and the domain extension.

Examples:

> hideEmail('example@example.com')
> 'e*****e@example.com'

> hideEmail('example+test@example.co.uk', hideFull)
> 'e**********t@e******.co.uk'
