Insert list in particular column! Help!

[vndywarhol]

Hello! I have a table 'employee' with data and with one empty column 'employee_department'.



I want to insert a list into this column. List contains integers:

depart_id_list = [3, 3, 3, 3, 4, 4, 3, 3, 2, 2, 2, ...]

I did the following:

for d in depart_id_list:
    cur.execute("INSERT INTO employee(employee_department) VALUES (%s)", [d])

But this is error. It seems to me that the logic of my query is that I insert "horizontally", and not "vertically", and all the missing values ​​are filled with null:

Error:
cur.execute("INSERT INTO employee(employee_department) VALUES (%s)", [d])
psycopg2.IntegrityError: null value in column "first_name" violates not-null constraint
DETAIL:  Failing row contains (1, null, null, null, null, null, null, 3).
