Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “ You want to put the Vyper files inside the contracts directory alongside 1_Storage.sol, 2_Owner.sol, and 3_Ballot.sol. Make sure the contracts directory is selected by right-clicking it.”

A block of code is set as follows:

from ape import accounts, project
import os
def main():
    password = os.environ["MY_PASSWORD"]
    dev = accounts.load("dev")
    dev.set_autosign(True, passphrase=password)
    contract = project.SimpleStorage.deploy(sender=dev)
    num_value = contract.retrieve.call()
    print(f"The num value is {num_value}")

Any command-line input or output is written as follows:

(.venv) $ export VOTER_PASSWORD=youraccountpassword
(.venv) $ export VOTER_ACCOUNT=voter1
(.venv) $ export PROPOSAL=0

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Click contracts under FILE EXPLORER and click 1_Storage.sol.”
