A Python library for interacting with Ethereum and EVM-compatible blockchains.
web3.py is a Python software development kit (SDK) designed to facilitate interaction with the Ethereum blockchain and other Ethereum Virtual Machine (EVM) compatible networks. It provides developers with a comprehensive set of tools to build decentralized applications (dapps), manage accounts, send transactions, interact with smart contracts, and query blockchain data. The library supports synchronous and asynchronous programming models, making it adaptable to various Python development environments.
The SDK includes extensive APIs covering Ethereum core functionality such as transaction handling, contract deployment and interaction, event filtering and subscriptions, middleware integration, and Ethereum Name Service (ENS) resolution. It also supports advanced features like beacon chain APIs, tracing, and gas price estimation. web3.py is widely used by developers familiar with Python who want to leverage Ethereum's capabilities without switching to other languages like JavaScript or Solidity.
What sets web3.py apart is its focus on Python ecosystem integration, including compatibility with Python 3.8 and above, and its active community support through Discord and GitHub. The project offers detailed documentation, quickstart guides, and migration resources to help developers onboard quickly. It is open source and encourages contributions, making it a reliable and evolving tool for Ethereum development. Developers can get started by installing the package via pip and following the quickstart guide to connect to Ethereum nodes and begin interacting with the blockchain.
Developers using Python face challenges when building Ethereum dapps due to the lack of a robust, native Python library that supports comprehensive blockchain interactions. Without such a tool, integrating smart contract calls, managing transactions, and querying blockchain data can be complex and error-prone.
Deploy and interact with Ethereum smart contracts using Python objects and methods.
Listen to blockchain events and logs with support for event subscriptions.
Customize request/response handling with middleware layers.
Developers use web3.py to create decentralized finance apps that interact with smart contracts for lending, borrowing, and trading.
Data scientists and analysts use web3.py to query blockchain data and build analytics dashboards.
DAO developers leverage web3.py to manage governance contracts and automate voting processes.
