Empty Json File

[praxis-dev]

Hi!

At 3:46:56 Patrick is creating a json file with a compiled code inside.

My file is empty. What do yo suggest?

from solcx import compile_standard, install_solc
import json

with open("./SimpleStorage.sol", "r") as file:
    simple_storage_file = file.read()
    print(simple_storage_file)

    install_solc("0.6.0")
    compiled_sol = compile_standard(
        {
            "language": "Solidity",
            "sources": {"SimpleStorage.sol": {"content": simple_storage_file}},
            "settings": {
                "outputSelection": {
                    "*": {"*": ["abi", "metadata", "evm.bytecode", "evm.sourceMap"]}
                }
            },
        },
    )

with open("compiled_code.json", "w") as files:
    json.dump(compiled_sol, file)

There is also a "ValueError: I/O operation on closed file." message in the Terminal.

Hello @vaporm
you have a typo here:

with open("compiled_code.json", "w") as files:
    json.dump(compiled_sol, file)

You are opening the file as "files" and then you use json.dump to "file" without "s" so the name have a mismatch.

Cheers.
