Python wrapper around the different PriceCypher APIs

Project description

PriceCypher Python SDK

Python wrapper around the different PriceCypher APIs.

Usage

Installation

Simply execute pip install pricecypher-sdk

Dataset SDK

import asyncio
from pricecypher import Datasets


async def handle_page(page, page_nr, last_page):
    """ This function will be called for each individual page of transactions that is received."""
    print(f'Handling page {page_nr}/{last_page}')
    print(f'Nr of transactions in page: {len(page)}')
    print(f'Handling page {page_nr}/{last_page} done')


async def main():
    async with Datasets(BEARER_TOKEN) as ds:
        # Specify desired columns to be requested for transactions 
        columns = [
            {'name_dataset': 'cust_group', 'filter': ['Big', 'Small'], 'key': 'group'},
            {'representation': 'cost_price', 'aggregate': 'sum', 'key': 'cost_price'}
        ]

        index = asyncio.create_task(ds.index())
        meta = asyncio.create_task(ds.get_meta(DATASET_ID))
        scopes = asyncio.create_task(ds.get_scopes(DATASET_ID))
        values = asyncio.create_task(ds.get_scope_values(DATASET_ID, SCOPE_ID))
        summary = asyncio.create_task(ds.get_transaction_summary(DATASET_ID))
        transactions = asyncio.create_task(ds.get_transactions(DATASET_ID, AGGREGATE, columns))

        print('datasets', await index)
        print('transactions', await transactions)
        print('meta', await meta)
        print('summary', await summary)
        print('scopes', await scopes)
        print('scope values', await values)

asyncio.run(main())

Printing debug logs

By default, debug log messages are not printed. Debug logs can be enabled using the following.

import logging

logging.basicConfig(level=logging.DEBUG)

Contracts

The Script, ScopeScript, and QualityTestScript abstract classes can be extended with their abstract methods implemented to create scripts usable in other services.

The ScopeScript in particular is intended for scripts that calculate values of certain scopes for transactions.

The QualityTestScript is intended for scripts that check the quality of a data intake and produce a standardized output that can be visualized and/or used by other services.

See the documentation on the abstract functions for further specifics.

Development

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

  • Python >= 3.9

Setup

The endpoints module models the different PriceCypher API endpoints. Each file represents a different API and the contents of each file are structured into the different endpoints that are provided by the API. Similarly, each file in the models module defines the models that are provided by the different APIs.

The SDK that this package provides is contained in the top-level package contents.

Deployment

  1. Execute python -m build to build the source archive and a built distribution.
  2. Execute python -m twine upload dist/* to upload the package to PyPi.

Snapshot

To deploy a snapshot release, follow the next steps instead.

  1. Add -pre to the version in setup.cfg.
  2. Execute python -m build -C--global-option=egg_info -C--global-option=--tag-build=dev.
  3. Execute python -m twine upload dist/*.
