In the Ethereum universe, there is a single, canonical computer (called the Ethereum Virtual Machine, or EVM) whose state everyone on the Ethereum network agrees on. An introduction to the Ethereum client APIs that let you interact with the blockchain from your application. Ethereum is a global, decentralized platform for money and new kinds of applications. On Ethereum, you can write code that controls money, and build applications accessible anywhere in the world. Pomocou funkcie glob v slučke foreach môžete robiť čokoľvek, čo je možné. V nasledujúcom príklade som tiež použil funkciu file_exists na kontrolu, či adresár existuje, skôr ako pôjdem ďalej.

Web3.py is a python library for connecting to these nodes. It does not run its own node internally. How do I choose which node to use?¶. Due to the nature

Your Web3.py instance may be further configured via middleware. Web3.py middleware is described using an onion metaphor, where each layer of middleware may affect both the incoming request and outgoing response from your provider.

Web3.py middleware is described using an onion metaphor, where each layer of middleware may affect both the incoming request and outgoing response from your provider. The documentation includes a visualization of this idea. Several middleware are included by default. Web3.py can help you read block data, sign and send transactions, deploy and interact with contracts, and a number of other features. Many of the typical things you’ll want to do will be in the w3.eth API, so that is a good place to start.

Several middleware are included by default. Here is an example of how one can use the pytest framework in python, Web3.py, eth-tester, and PyEVM to perform unit tests entirely in python without any additional need for a full featured ethereum node/client. To install needed dependencies you can use the pinned extra for eth_tester in web3 and pytest: Web3.py can help you read block data, sign and send transactions, deploy and interact with contracts, and a number of other features.
