Python keeps inserting NULL values into table

[card51shor]

db.execute("INSERT INTO users (username, password) VALUES (:username, :password)", {"username":username, "password":password})

What should this be then? I can't figure it out with the documentation u sent. Before it used to give me a syntax error before i corrected it now I'm not getting an error but the values are NULL still.


Tried this:

db.execute("INSERT INTO users (username, password) VALUES (%s, %s)", ("username", "password",))

Now I get an error when I click the register button:

AttributeError: 'tuple' object has no attribute 'keys'
