Easiest way to clean email address in python

Question

I am having issues with emails address and with a small correction, they are can be converted to valid email addresses.

For Ex:

%20adi@gmail.com, --- Not valid
'sam@tell.net,  --- Not valid
(hi@telligen.com),  --- Not valid
(gii@weerte.com),  --- Not valid
:qwert34@embright.com,  --- Not valid
//24adifrmaes@microsot.com  --- Not valid
tellei@apple.com    ---  valid
...

I could write "if else", but if a new email address comes with new issues, I need to write "ifelse " and update every time.

What is the best way to clean all these small issues, some python packes or regex? PLease suggest.

Answer 1

You can do this (I basically check if the elements in the email are alpha characters or a point, and remove them if not so):

emails = [
    'sam@tell.net', 
    '(hi@telligen.com)', 
    '(gii@weerte.com)',  
    ':qwert34@embright.com',  
    '//24adifrmaes@microsot.com',
    'tellei@apple.com'
    ]

def correct_email_format(email):
    return ''.join(e for e in email if (e.isalnum() or e in ['.', '@']))

for email in emails:
    corrected_email = correct_email_format(email)
    print(corrected_email)

output:

sam@tell.net
hi@telligen.com
gii@weerte.com
qwert34@embright.com
24adifrmaes@microsot.com
tellei@apple.com
