Pythark
Ark API Wrapper in Python.
Built with
Installation
Pythark uses Arky to create a new transaction, if you want to use this feature you will need to install Arky too.
Since Arky can works with the nano s ledger now, you need to install these dependencies :
sudo apt-get install python3-dev libusb-1.0-0-dev libudev-dev
pip install pythark
pip install https://github.com/ArkEcosystem/arky/archive/aip11.zip
Application Example
- PytharkFlask - Example of a web application using Flask and Pythark
- PytharkCLI - Example of a CLI application using Click and Pythark
Usage
Network
Since the version 0.1.3, Pythark can now interact with others network than the main one. If you want to query on the devnet for example, you will need to specify it like this :
from pythark import Peer
# It's not mandatory to specify the network, by default the main network will be used.
# So : peer = Peer() is still correct.
peer = Peer("dev") # or peer = Peer(network="dev")
print(peer.get_peers())
>>> {'success': True, 'peers': [{'ip': '167.114.29.62', 'port': 4002, 'version': '1.1.0', 'errors': 0, 'os': 'linux4.4.0-79-generic', 'height': 2056284, 'status': 'OK', 'delay': 33},
}...
You can use this with all the Pythark functions.
The currently available networks are the following : main, dev, dark, kapu.

TODOS
- Core code.
- Write documentation.
- Basic docs written, need to polish.
- Unit testing.
- Check if it can be better.
- Package it.
- Seems OK right now, distributed on PyPi, but have to be sure it's OK for everyone on X python version and differents OS.
- Travis.
- Missing support for python 3.2.
- OSX Support ?
- Windows support ?
- Better errors handling for the models methods.
