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).

PyOTA is compatible with Python 3.6, 3.5 and 2.7.
To install the latest version:
pip install pyota
Optional C Extension¶
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]
Installing from Source¶
- Create virtualenv (recommended, but not required).
git clone https://github.com/iotaledger/iota.lib.py.git
pip install -e .
Running Unit Tests¶
To run unit tests after installing from source:
python setup.py test
PyOTA is also compatible with tox, which will run the unit tests in different virtual environments (one for each supported version of Python).
To run the unit tests, it is recommended that you use the detox library. detox speeds up the tests by running them in parallel.
Install PyOTA with the
test-runner extra to set up the necessary
dependencies, and then you can run the tests with the
pip install -e .[test-runner] detox -v
PyOTA’s documentation is available on ReadTheDocs.
If you are installing from source (see above), you can also build the documentation locally:
Install extra dependencies (you only have to do this once):
pip install '.[docs-builder]'
To install the CCurl extension and the documentation builder tools together, use the following command:
pip install '.[ccurl,docs-builder]'
