从给定文本中提取电子邮件

Question

I am trying to extract a list of emails from a given text. Most of emails has the following syntax:

 "Last_name, First_Name (First-name)" <last_name.first_name@domain.xxx>
or
"Last_name, First_Name (XXXX)" <last_name.first_name@domain.xxx>

My goal is to extract the whole emails including the first part, meaning the "Last_name, First_Name (XXXX)".

To extract the list of emails, I have used the following regex:

"(<?[a-z0-9!#$%&*+\/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+\/=?^_`"
"{|}~-]+)*(@|\sat\s)(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?(\.|"
"\sdot\s))+[a-z0-9](?:[a-z0-9-]*[a-z0-9]>?)?)"

which extract only the emails without the first part. Meaning that extract only the:

<last_name.first_name@domain.xxx>

I have tried several variations of the regex to extract the first part but unfortunately they doesn't work.

Please do not hesitate If you have any suggestion. Thank you in advance.

Answer 1

First, check that link where you can test your regex with a nice memo around it

https://regex101.com

Then, something like

"[a-zA-Z_]+, [a-zA-Z_( )]+"

Should capture the first Part, maybe be you can give us some more testing text ?

Answer 2

 >>> import re
 >>>
 >>> emailLine='"Last_name, First_Name (First-name)" <last_name.first_name@domain.xxx>'
 >>>
 >>> re.findall('^\"([^,]*?),\s([^"]*?)"\s<([^>]*?)>',emailLine)

 [('Last_name', 'First_Name (First-name)', 'last_name.first_name@domain.xxx')]
