Ethereum Python Library Issues with Binance Account Login

As a developer, it’s always frustrating when your favorite libraries fail to work as expected. Recently, we have encountered an issue with the get_account() function of the etherscan.io library on Binance, which is causing errors while trying to log in to the exchange.

The Problem:

When using the get_account() function from the etherscan.io library, you are trying to retrieve a user account object. However, this object is a coroutine, which means it has an internal state that is not yet initialized when you call it. This leads to the following errors:

• TypeError: 'coroutine' object is not subscriptable: The info['balances'] line attempts to access the balances property of a coroutine, which does not make sense.

• RuntimeWarning: coroutine 'get_account' is used before it is defined

Solutions:

To resolve this issue, you can use one of the following approaches:

Approach 1: Use the etherscan.io library’s login() function

The etherscan.io library provides a simpler way to log in to an exchange without having to worry about coroutines.

from Etherscan import get_account


def login_to_binance():

    user = await get_account('0xYourUsername')

    return user







Usage:

user = login_to_binance()

Approach 2: Use a Non-Coroutine Implementation of get_account()

If you need to use the get_account() function of the etherscan.io library, you can create a non-cryptographic implementation that returns an object instead of a coroutine.

from Etherscan import get_account


class BinanceAccount:

    def __init__(self, user_id):

        self.user = get_account(user_id)


def login_to_binance():

    account = BinanceAccount('0xYourUsername')

    return account.user



Usage:

account = login_to_binance()

Approach 3: Use a Third-Party Library with Non-Coroutine Implementation

If you’re still stuck, consider using a third-party library like py-scan that has a non-cryptographic implementation of the get_account() function.

import foot_scanner


def login_to_binance():

    user = py_scanner.get_user('0xYourUsername');

    return user



Usage:

user = login_to_binance()

Conclusion:

In conclusion, using the etherscan.io library’s get_account() function on Binance can be tricky due to its coroutine nature. By following these approaches or using a third-party library with a non-cryptographic implementation, you should be able to resolve this issue and continue developing your Ethereum applications.
