The OPs example has a formatted string, no idea what is in it...
My example creates a tuple out of each of the records you want to
insert and uses them in the bind variables.
You can do a loop through hostlist and do a single execute on each one
if you want. It won't make a large impact.
The [(i,)[0] for i in hostlist] was mainly directed to you because
your structure ends up being a tuple inside a list which doesn't work
for cx_Oracle. You need a straight tuple to bind to the statement.
My code creates a series of usable tuples for the executemany
function.
HTH,
Chris
