Why I need to use reg-ex if I can use for loops s = "Please contact [e-mail] for assistance" email = [i for i in s.split(' ') if '@' in i]

Answer 1

cause in other cases you can have @ symbol in no email words forma example. Regular expressions can specify a more complex email format, analysing all the components in an email, not only that it has an @

Answer 2

No. There was another name on that response earlier; it switched around 13:00 UTC.

That answer also has a typo; it needs a \ for the 2nd 'w'.

Answer 3

I understand trouble with for loop, but also you have mistake.
If we have sample like this:
s= 'Sasha Veledzimovich [e-mail], [e-mail], [e-mail].'
You code will provide e-mail with dot at the end.

We can fix it pat=r"[\w\.-]+@[w\.-]+\.[\w]+"

Also you have parenthesis. They are not nessessary. If we use re.findall we have emails separated by groups. For example : ('python', 'gmail.url', '.com')

Answer 4

Did you just answer your own question like it was to somebody else?
