python sqlite insert named parameters or null

Question

I\'m trying to insert data from a dictionary into a database using named parameters. I have this working with a simple SQL statement e.g.

SQL = \"INSERT INTO sta         


        

Answer 1

Use None to insert a NULL:

dict = {'location': 'somewhere', 'arrival': '1000', 'departure': None}

You can use a default dictionary and a generator to use this with executemany():

defaults = {'location': '', 'arrival': None, 'departure': None}

c.executemany(SQL, ({k: d.get(k, defaults[k]) for k in defaults} for d in your_list_of_dictionaries)
