Answer 1

Just use it in db.search

from tinydb import TinyDB, Query
db = TinyDB('db.json')
ddd = Query()
db.insert({'state': 'free', 'field': 1})
db.insert({'state': 'n', 'field': 2})
db.insert({'state': 'free', 'field': 3})
kl = 'free'
output = db.search(ddd.state == kl)
print(output)

output

[{'state': 'free', 'field': 1}, {'state': 'free', 'field': 3}]
