Python Ethereum Library Issues with Binance Account Login

As a developer, it’s always frustrating when your favorite libraries don’t work as expected. Recently, we encountered an issue with the get_account() function of the etherscan.io library on Binance, which causes errors when trying to connect to the exchange.

The Issue:

When you use the get_account() function of the etherscan.io library, you are trying to retrieve a user account object. However, this object is a coroutine, meaning that 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 line info['balances'] tries to access the balances property of a coroutine, which doesn’t make sense.

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

Workarounds:

To solve this problem, you can use one of the following approaches:

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

The etherscan.io library provides an easier way to connect to an exchange without having to worry about coroutines.

from etherscan import get_account
def login_to_binance():
user = wait 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 from 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 a non-coroutine implementation

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

import py_scanner
def login_to_binance():
user = py_scanner.get_user('0xYourUsername')
return user

Usage:
user = login_to_binance()

Conclusion:

In conclusion, using the get_account() function from the etherscan.io library 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 solve this problem and continue developing your Ethereum applications.

API Documentation:

• get_account(user_id): Retrieves an account object from the Ethereum network.

• login_to_binance(): Connects to the Binance exchange and returns a user object.

• BinanceAccount(…): A non-cryptographic implementation of theget_account()` function that returns an object instead of a coroutine.
