How do i remove “default”?

Question

i have been having some problems understanding where i went wrong in my codes. I have been trying to print out the output of my codes into a json file but apparently, my list is empty because it has this "default" thing printed out. How do i change it such that the books map has Book Id and Serial no. part into the empty {} instead? I already did my own research but unfortunately none of the forums that i went to provided an answer.

Here's my output:

{"books": {}, "_default":
  {
   "1": {Book ID: XXXX bookid 1 XXXX},
   "2": {Serial No.: XXX serialno 1 XXXX}
  },
 {
   "1": {Book ID: XXX bookid 2 XXXX},
   "2": {Serial No.: XXX serial no. 2 XXX}
 }
}

Here are my codes:

with open("/home/pi/Desktop/json/pillar1.json", 'w+'):
        db = TinyDB('/home/pi/Desktop/json/pillar1.json')
        table = db.table('Books')
        db.insert_multiple([{'Book ID' : variable}, {'Serial no' : variable]}])

There is always a _default table, described here

Operations like db.insert_multiple will happen on the _default table. Which you actually show in your file sniplet correctly.

Table "books" is empty

"books": {}

and the inserts have take place on the _default table

"_default":
  {
   "1": {Book ID: XXXX bookid 1 XXXX},
   "2": {Serial No.: XXX serialno 1 XXXX}
  },
 {
   "1": {Book ID: XXX bookid 2 XXXX},
   "2": {Serial No.: XXX serial no. 2 XXX}
 }

In order to insert in a table, you can do the following:

with open("/home/pi/Desktop/json/pillar1.json", 'w+'):
        db = TinyDB('/home/pi/Desktop/json/pillar1.json')
        table = db.table('books')
        table.insert_multiple([{'Book ID' : variable}, {'Serial no' : variable]}])

note the table.insert_multiple in stead of db.insert_multiple

[EDIT]

you can set your own default table as described here
