Assuming that each tuple is the same length and goes into the same table
and columns, something like this will do the trick:

sql = "insert into tablename(column1,column2,column3) values(?,?,?)"
cursor.executemany(sql, list_of_tuples)

If you don't know the number of columns at design time, you'll need to
fill the values(...) clause on the fly with the correct number of
question marks, and you'll have to build the list of column names
somehow, too, but the basic idea is the same.

HTH,
