I don't use MySQL but that's how others work.
Each list item is a record, each record a tuple
of field values.

If you don't fetch too many records at once.
This is a test of my word database using ODBC
and MS-ACCESS (the SQL is very simple since
all the actual work is done in MS-ACCESS, Python
is just retrieving the final results).
import dbi
import odbc
con = odbc.odbc("words")
cursor = con.cursor()
cursor.execute("SELECT * FROM signature_anagram_summary")
results = cursor.fetchall()
Here, results (the recipient of .fetchall) is a list of tuples.
The contents are:
[(9, 10, 'anoretics', '10101000100001100111000000'),
(9, 10, 'atroscine', '10101000100001100111000000'),
(9, 10, 'certosina', '10101000100001100111000000'),
(9, 10, 'creations', '10101000100001100111000000'),
(9, 10, 'narcotise', '10101000100001100111000000'),
(9, 10, 'ostracine', '10101000100001100111000000'),
(9, 10, 'reactions', '10101000100001100111000000'),
(9, 10, 'secration', '10101000100001100111000000'),
(9, 10, 'tinoceras', '10101000100001100111000000'),
(9, 10, 'tricosane', '10101000100001100111000000')]

I don't know, I don't get column names. It looked like
from your example that you can use names, I would have
to use indexes, such as results[3][2] to get 'creations'.
Maybe MySQL returns dictionaries instead of tuples.

Yeah, they die. You would have to have the function return
the results list and indx, then you could use it's contents
as criteria for further queries.
So you might want to say
name_find_results,indx = name_find(namefrag)
> If they die, how do I get around this?
Add 'return results,indx' to the function. Or better still,
just return the record the user selected
return results[indx]
You wouldn't need indx anymore since there's only 1 record.
