pytezos 2.2.2

Python toolkit for Tezos

PyTezos

Python SDK for Tezos: RPC, cryptography, operations, smart contract interaction

Requirements

• git
• python 3.6+
• pip 19.0.1+

You will also probably need to install several cryptographic packets.

Linux

Use apt or your favourite package manager:

$ sudo apt install libsodium-dev libsecp256k1-dev libgmp-dev

MacOS

Use homebrew:

$ brew tap cuber/homebrew-libsecp256k1
$ brew install libsodium libsecp256k1 gmp

Windows

The recommended way is to use WSL and then follow the instructions for Linux, but if you feel lucky you can try to install natively:

1. Install MinGW from https://osdn.net/projects/mingw/
2. Make sure C:\MinGW\bin is added to your PATH
3. Download the latest libsodium-X.Y.Z-msvc.zip from https://download.libsodium.org/libsodium/releases/.
4. Extract the Win64/Release/v143/dynamic/libsodium.dll from the zip file
5. Copy libsodium.dll to C:\Windows\System32\libsodium.dll

Installation

$ pip install pytezos

Google Colab

>>> !apt install libsodium-dev libsecp256k1-dev libgmp-dev
>>> !pip install pytezos

Usage

Read quick start guide, or just enjoy surfing the interactive documentation using Python console/Jupyter:

>>> from pytezos import pytezos
>>> pytezos
