If you have other parameters in the query, beyond the IN list, then the following extension to JG's answer may be useful.

ids = [1, 5, 7, 213]
sql = "select * from person where type=%s and id in (%s)"
in_ids = ', '.join(map(lambda x: '%s', ids))
sql = sql % ('%s', in_ids)
params = []
params.append(type)
params.extend(ids)
cursor.execute(sql, tuple(params))

That is, join all the params in a linear array, then pass it as a tuple to the execute method.
