Newbie question.

Why is it that there's a bazillion different types of screws? Why can't we just always use one standard screw type? Are there advantages/disadvantages to the different types? Are there times when one type is preferred over another?

Help me understand why there isn't one screw to rule them all.


Question: multidimensional array to database in python
Answer: Use the cursor.executemany() method to insert a sequence of rows in one go:

query_string = 'INSERT INTO sample VALUES (?, ?, ?)'

c.executemany(query_string, array2d)
conn.commit()


Don't forget to conn.commit() the transaction.

I've not bothered with formatting the SQL parameters here, for demonstration purposes; you don't really want to do so here anyway, as your number of columns is fixed at well (from the CREATE TABLE definition).
