Intro

biothings_client is an easy-to-use Python wrapper to access any Biothings.api -based backend service. Currently, the following clients are available:

• gene - The client for MyGene.Info, which provides access to gene objects.
• variant - The client MyVariant.Info, which provides access to genetic variant objects.
• chem - The client for MyChem.Info, which provides access to chemical/drug objects.
• disease - The client for MyDisease.Info, which provides access to disease objects.
• taxon - The client for t.biothings.io, which provides access to taxon objects.

Requirements

python >=2.7 (including all python3 versions)

(It may still work under python 2.6, but it's not supported any more.)

requests (install using "pip install requests")

Optional dependencies

• pandas (install using "pip install pandas") is required for returning a list of variant objects as DataFrame.
• requests_cache (install using "pip install requests_cache") is required for local caching of API requests.

Installation

Option 1

pip install biothings_client

Option 2

download/extract the source code and run:

python setup.py install

Option 3

install the latest code directly from the repository:

pip install -e git+https://github.com/biothings/biothings_client.py
