How to convert a tuple to a string in Python?

Question

After a MySQL select statement, I am left with the following:

Click to copy

set([('1@a.com',), ('2@b.net',), ('3@c.com',), ('4@d.com',), ('5@e.com',), ('6@f.net',), ('7@h.net',), ('8@g.com',)])

What I would like to have is a

Click to copy

emaillist = "\n".join(queryresult)

to in the end, have a string:

Click to copy

1@a.com
2@b.net
3@c.com
etc

What would be the proper way to convert this nested tuple into string?

Answer 1

As long as you're sure you have just one element per tuple:

Click to copy

'\n'.join(elem[0] for elem in queryresult)
