Web3.py

Installation

  • pip install web3

Concepts

  • All of the smart contract functions are listed under the contract.functions namespace within the assigned Web3 contract. For example, we can call contract.functions.myFunction() if the contract implements myFunction().
# For ERC20 token
print(contract.functions.name().call())
# > OMG Token

Troubleshooting

  • Error related to MS Visual C++ 14.0 or greater is missing:
error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/

- solution: install libs using pip: `conda install libpython m2w64-toolchain -c msys2` as __administrator__ in command prompt.
