PyTezos is a Python library for interacting with Tezos blockchain and testing smart contracts.

With PyTezos, you can do the following:

• Accessing blockchain data
• Injecting transactions into the blockchain
• Originate contracts
• Packing and signing Michelson data
• Testing contracts

And many more.

<aside> 💡 This tutorial uses hangzhounet. As tezos is upgradable, new testnets appear after every 3 months and older ones are made absolute. So, always use the latest testnet.
