pip install pythonfiledatastore

Usage:

>>> from pythonfiledatastore import datastore_invoke 

General Instructions:

>>> print(datastore_invoke(0))

2 for Read (--client --key --filepath(optional)) 
3 for Delete (--client --key --filepath(optional)) 
4 for Reset (--client --filepath(optional))

Create Operation with file path

>>> print(datastore_invoke(1, client = "hunch" , key = "employee_data", value = '{"employee":"siam"}', filepath = "/Users/user_name/Desktop/"))
Create Operation Done

Create Operation

>>> print(datastore_invoke(1, client = "hunch" , key = "employee_data", value = '{"employee":"siam"}'))
Create Operation Done

>>> print(datastore_invoke(1, client = "hunch" , key = "employee_data_temp", value = '{"employee":"ragoish"}', ttl = 30 ))
Create Operation Done

Read Operation

>>> print(datastore_invoke(2, client = "hunch" , key = "employee_data"))
For key | employee_data | value  - {'employee': 'siam'}
