Iḿ stuck with this problem

When I check this in my console is working out !! so I don't understand the error that I get.

sets_email.py 
import re

# Example:
# >>> find_email("kenneth.love@teamtreehouse.com, @support, ryan@teamtreehouse.com, test+case@example.co.uk")
# ['kenneth@teamtreehouse.com', 'ryan@teamtreehouse.com', 'test@example.co.uk']

def find_emails(basura):
        a = re.findall(r'[-\w\d.]+@[-\w\d.]+', basura)
        return a

hi igor,

You get that error because if you look at the emails provided in this example, you will find there is a "+" character in the last email (test+case@example.co.uk) that we need to include in the first set before "@" symbol .. so we can capture that email too with our regular expression..

So you could modify your re to look like this and this will work for the current challenge..

def find_emails(basura):
    a = re.findall(r'[-+\w\d.]+@[-\w\d.]+', basura)
    return a

you are welcome, igor..

Please, could you tell me the error message that appears to you?

I tested the code and it's working fine, I get a list of 3 emails:

['kenneth.love@teamtreehouse.com', 'ryan@teamtreehouse.com', 'test+case@example.co.uk']

Hi Karim!!

The error is not very helpful :

Bummer: TabError: return a

Hi igor,

may be it's indentation problem.. Please refer to this solution: Bummer: TabError :inconsistent use of tabs and spaces

Answer by Steven Parker:

Python allows you to indent using spaces or tabs, but you must pick one or the other and use it consistently.

Please, try to rewrite your code using only tabs or spaces for indentation and see if it works..

You are welcome, igor :)

Python rely on indentation for code blocks. Sometimes this could get out of hands if not doing it correctly.

So, most Python programmers follow Style Guide for Python Code -also known as "PEP 8"-. Its goal is to promote readability and consistency in Python code bases.

Also there is a course here at "TreeHouse" explaining this, you can find it here: Write Better Python

In the end, I'm glad that you were able to solve it :)
