A simple database in python that is built on python dictionary and stored using json

This is a simple Database implementation built on top of json The idea behind was found at https://medium.freecodecamp.org/how-to-write-a-simple-toy-database-in-python/ by Palash Bauri

The implementation is simple
A database here is treated nothing more than a python dictionary.
But after every change in the in memory dictionary database, the database is written to a file specified
when creating an instance of the database object.
This file can then be loaded back in memory when the database is called again after it has been deleted.

Methods to be used are
load(self, location)
        this loads the database file into a memory as dictionary

get(self, key)
        this returns the value stored in memory with the key provided

delete(self, key)
        This removes the key and related value from the database

flush(self)
        This clears the entire database content

dumpdb(self)
        This writes the dictionary in memory database to a file

_load(self)
        An internal method that loads the database from file

variables used are

self.location
        This is the path and filename of the database file

Example

---

mydb = joedb.JoeDb("mydb.db") mydb.set("Hello", "World") mydb.get("Hello")

outputs: "World"
