This is the official Python library for the IOTA Core.

It implements both the official API, as well as newly-proposed functionality (such as signing, bundles, utilities and conversion).

If you want to get involved in the community, need help with getting setup, have any issues related with the library or just want to discuss Blockchain, Distributed Ledgers and IoT with other people, feel free to join our Slack.

You can also ask questions on our dedicated forum.

If you encounter any issues while using PyOTA, please report them using the PyOTA Bug Tracker.

PyOTA is compatible with Python 3.6, 3.5 and 2.7.

To install the latest version:

pip install pyota

PyOTA has an optional C extension that improves the performance of its cryptography features significantly (speedups of 60x are common!).

To install this extension, use the following command:

pip install pyota[ccurl]

1. Create virtualenv (recommended, but not required).
2. git clone https://github.com/iotaledger/iota.lib.py.git
3. pip install -e .

To run unit tests after installing from source:

python setup.py test

PyOTA is also compatible with tox:

pip install tox
tox

PyOTA's documentation is available on ReadTheDocs.

If you are installing from source <readme-installing-from-source>, you can also build the documentation locally:

1. Install extra dependencies (you only have to do this once):

   pip install '.[docs-builder]'

   Tip

   To install the CCurl extension and the documentation builder tools together, use the following command:

   pip install '.[ccurl,docs-builder]'

2. Switch to the docs directory:

   cd docs

3. Build the documentation:

   make html
