I have two database and want to fetching all tables in only one database. If i run these commands

cur.execute("SELECT name FROM sqlite_master")

and

cur.execute("SELECT name FROM sqlite_schema")

both result are same and fetching all tables in all databases. I want to fetch only from one database.

full cade is here

      con=sqlite3.connect("Nested_Database_try")
