How to split string of emails with different domains and no separator

Question

How can one separate a string of emails with no separator and different domains/number of letters after ‘@‘?

[email protected]@[email protected]@us.org

Is it possible to structure: If ends with .br or .se: separate there Else, separate after .com ?

Answer 1

One possibility is to use regular expression (regex101):

import re

s = "[email protected]@[email protected]@us.org"

emails = re.findall(r"[^@]+@[^@]+(?:\.com|\.se|\.br|\.org)", s)
print(emails)

Prints:

['[email protected]', '[email protected]', '[email protected]', '[email protected]']
