dictstore

dictstore is a simple local data store for Python that aims to provide an interface similar to a python dictionary.

Getting Started

Installation

pip install dictstore

Usage

# file: sample_1.py

from dictstore import DictStore

data = DictStore()

d[1] = 45

# file: sample_2.py

from dictstore import DictStore

data = DictStore()

print(d[1])

# output: 45

Considerations

• dictstore uses an in memory dictionary to support fast reads

• using multiple DictStore instances for the same data file is not supported. Instead DictStore class returns the same instance for the same data file throughout the python code (Singleton behaviour).

• dictstore is best suited for CLIs or similar applications where values have to be remembered accross multiple runs.

• The data file is a plain readable text file and no encryption is offered by dictstore.

• dictstore might not be the fastest datastore, its promise is to get the work done and nothing more.

• dictstore will evaluate the type of value for all the nested objects in a given value, this is done using a Tree.

• This project has not be tested for concurrency safety. Please be cautious when using in projects involving multi-anything.

Keys

All Hashable Data Types are supported as keys.

Hashable Data Types

Name	Type
String	str
Integer	int
Float	float
Tuple	tuple

Values

Dictstore uses ast package and ast.literal_eval under the hood, so currently all the data types supported by ast.literal_eval except Ellipsis are supported as values.

strings, bytes, numbers, tuples, lists, dicts, sets, booleans, None.
