# The first solution  that comes my head is iter about it and use append, pop or delete but
# there is a more elegant solution with a  collection "datatypes" is an awesome feature.

"""
Reference Python cookbook 
If you have tuples an awesome feature is unpacking from python, sometimes you need to unpacking tuples without know the index.
x,y,z = (1,2)
This raise an error about

ValueError: need more than 2 values to unpack

This is because you are unpacking more than values that expect.

-- To know if x column have elements repeated

SELECT `name_column`, COUNT(1) as CNT 
FROM `name_column` 
GROUP BY `n`
HAVING COUNT(1) >1;
