CRUD

Create, Update

Create and update is handled using same functions.

put, putall

If key doesnt exist it would be created, else the value updated.

# add or update memory using :put
# method :put may be chained
memory\
    .put('One', 1)\
    .put('Two', 2)

# or by using :putall
memory.putall({
    'three': 3,
    'Four': 4
})

Read

# read from memory using :get
two = memory.get('Two')

# output: 2

Delete

# delete keys using :delete
memory.delete('Two', 'Four')

# or clear the whole memory using :clear
memory.clear()

Method :delete takes one or more keys as parameters

Create a template

A template has two methods that need to be overwridden

def save(self, data: dict):
    ...

def load(self) -> dict:
    ...
