Library for working with NEO related data in Python, without database dependencies.
Datatypes like UInt160, KeyPair, BigInteger and basic string to address and address to UInt160 methods
Includes a useful cli-tool np-utils (see help with np-utils -h)
Compatible with Python 3.5+
Used by neo-python
np-utils examples:
$ np-utils -h
usage: np-utils [-h] [--version] [--address-to-scripthash address]
[--scripthash-to-address scripthash] [--create-wallet]
optional arguments:
-h, --help show this help message and exit
--version show program's version number and exit
--address-to-scripthash address
Convert an address to scripthash
--scripthash-to-address scripthash
Convert scripthash to address
--create-wallet Create a wallet
$ np-utils --create-wallet
{
"private_key": "KwJqCbjsmGUCqbkp83Nxi9MJ9mA7F8EN4tebJVWjYZBEoWCNxCaF",
"address": "AHVvg26CNz1vxteJfeHy4R8P4VN8SydCM6"

You need Python 3.5 or higher!
You can install neocore from PyPI with easy_install or pip:
$ pip install -U neocoreAlternatively, if you want to work on the code, clone this repository and setup your venv:
Clone the repo: git clone https://github.com/CityOfZion/neo-python-core.git
Create a Python 3 virtual environment and activate it:
$ python3 -m venv venv
$ source venv/bin/activateThen install the requirements:
$ pip install -e .
$ pip install -r requirements_dev.txtUseful commands
$ make lint
$ make test
$ make coverageRelease checklist
(Only for admins)
Releasing a new version on GitHub automatically uploads this release to PyPI. This is a checklist for releasing a new version:
# Only in case you want to increase the version number again (eg. scope changed from patch to minor):
bumpversion --no-tag minor|major
# Update ``HISTORY.rst`` with the new version number and the changes and commit this
vi HISTORY.rst
git commit -m "Updated HISTORY.rst" HISTORY.rst
# Set the release version number and create the tag
bumpversion release
# Increase patch number and add `-dev`
bumpversion --no-tag patch
# Push to GitHub, which also updates the PyPI package
git push && git push --tagsHistory
