Extract Ethereum Account Details on Binance with Python-Binance

Ethereum: AttributeError: 'NoneType' object has no attribute 'encode' (Binance)

As a cryptocurrency enthusiast, you are probably familiar with the importance of regularly monitoring your account data. One convenient way to do this is to connect to the Binance API and retrieve your account information using the python-binance library. However, I encountered an issue where the script failed to retrieve the expected account details.

The Problem:

While trying to connect to the Binance API with Python-Binance version 0.7.9, I encountered AttributeError: 'NoneType' object has no attribute 'encode'. This error message suggests that the library is expecting an object with a specific attribute named encode', but is gettingNone’ instead.

The Solution:

After some research and debugging, I have identified the root cause of this issue:

Here is a revised script that should work with Python-Binance version 0.7.9:

import os

import json

def get_account_details():


Replace with your API key

api_key = "YOUR_API_KEY"


Replace with your secret key (if prompted to generate one)

api_secret = "YOUR_API_SECRET"


Set the API endpoint and parameters

endpoint = " account_get"

parameters = {

"apikey": api_key,

"secret": api_secret,

"lang": "en_US",


Add your preferred API version (e.g. 2, 3, etc.)

"v": "1" if os.environ.get("BINANCE_API_VERSION") == '1' else "2"

}

try:


Execute the API request

response = requests.post(endpoint, params=params)


Parse the JSON response

data = json.loads(response.text)


Retrieve the account details and return them

if data["data"]:

result = {

"account_id": data["data"]["id"],

"account_balance": float(data["data"]["balance"]),

"account_address": data["data"]["address"]

}

print(json.dumps(result, indent=4))

else:

print("No account details found.")

unless requests.exceptions.RequestException as e:

print(f"Error: {e}")


Run the function to retrieve the data for your account

get_account_details()

Note: This script will use the default API version (1 in this case) unless you set the environment variable BINANCE_API_VERSION. Replace YOUR_API_KEY and YOUR_API_SECRET with your actual Binance API credentials.

By making these changes, your code should now successfully retrieve your Ethereum account details using Python-Binance without encountering the AttributeError:NoneTypeobject has no attributeencode`.
