a tip: you can pass the arguments to function as dictionary, so
if you store the connection arguments anywhere, you use this
form:
conndsc = {'host': 'localhost', 'user': 'root', 'port': 3306, ....}
con = mdb.connect(**conndsc)
My personal opinion, but it's easyer to use the cursor if you
have dictionary-like cursor:
> with con:

cur = con.cursor(mdb.cursors.DictCursor)
In this case you can reference the name of the table column,
instead of index of result, in your example:
row['descrip']
> cur.execute("SELECT descrip FROM table LIMIT 1")
> rows = cur.fetchall()
if you want to fetch only one row, you can use cur.fetchrow(),
which gives only one row, and you don't need to iterate that

as Benn Finney wrote, the use of split() above is wrong.
I think you need some kinf of this:
" ".join([f.strip() for f in row[0].replace("\n", " ").split()])
but it depends what you want.
