Python - 'sqlite3.InterfaceError: Error binding parameter 0 - probably unsupported type.' when insert data into table using sqlite3 python

Question

I tried to put data in to a table using variabels, as you can see down below in the code. When I'm running this piece of code I get the following error:

What I want the code to do is, get the data out of the parameters i'm giving in to the function insert_data. And then using the wildcard questionmark symbol. To get the option to use the variabels as data. Not quite sure if it's the most propper way of doing so. But it does work in other occations. I just don't get why it does not work in this piece of code.

Traceback (most recent call last):
  File "{path}", line 65, in <module>
    insert_data()
  File "{path}", line 56, in insert_data
    query ("INSERT INTO computers (name, os, mac_addr) VALUES "

Answer 1

The commas (,) terminating the set statments (eg name = platform.uname()[1],) cast the variables as tuples.
