dbnomics 1.2.1

DBnomics Python Client

DBnomics Python client

Access DBnomics time series from Python.

This project relies on Python Pandas.

Tutorial

A tutorial is available as a Jupyter notebook.

Use with a proxy

This Python package uses requests, which is able to work with a proxy (HTTP/HTTPS, SOCKS). For more information, please check its documentation.

Install

pip install dbnomics

See also: https://pypi.org/project/DBnomics/

Development

To work on dbnomics-python-client source code:

git clone https://git.nomics.world/dbnomics/dbnomics-python-client.git
cd dbnomics-python-client
pip install -r requirements.txt
pip install -r requirements-dev.txt
pip install -e .

If you plan to use a local Web API, running on the port 5000, you'll need to use the api_base_url parameter of the fetch_* functions, like this:

dataframe = fetch_series(
    api_base_url='http://localhost:5000',
    provider_code='AMECO',
    dataset_code='ZUTN',
)

Or globally change the default API URL used by the dbnomics module, like this:

import dbnomics
dbnomics.default_api_base_url = "http://localhost:5000"

Open the demo notebook

Install jupyter if not already done, in a virtualenv:

pip install jupyter
jupyter notebook index.ipynb

Tests

Run tests:

# Only once
pip install -r requirements.txt
pip install -r requirements-test.txt
pip install -e .

pytest

# Specify an alterate API URL
API_URL=http://localhost:5000 pytest

Release

To release a version on PyPI:

• merge one or many feature branches into master (no need to do a release for every feature...)
• update setup.py incrementing the package version (we use Semantic Versioning so determine if it's a major, minor or patch increment)
• ensure the changelog is up to date
• git commit setup.py CHANGELOG.md -m "Release"
• create a Git tag with a v before version number and push it (git tag v1.2.0; git push; git push --tags)
• the CI will run a job to publish the package on PyPI at https://pypi.org/project/DBnomics/

It's advised to do pip install -e . to let your virtualenv know about the new version number.
