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('[email protected]')
> 'e*****[email protected]'

> hideEmail('[email protected]', hideFull)
> 'e**********t@e******.co.uk'
