Can someone please explain to me what is wrong with this code? I get the “parameters are of unsupported type” error. Is it not possible to feed a list into cursor.executemany? The type of the column is float not null.
random_numbers = [ 1, 2, 3, ] cursor.executemany('INSERT INTO Table (Column) VALUES (?)', random_numbers)

Answer
The values for cursor.executemany
must be a sequence of tuples:
cursor.executemany('INSERT INTO Table (Column) VALUES (?)', [(n,) for n in random_numbers])
This is a logical extension of cursor.execute
requiring a single tuple
for the values argument.
