Ethereum: API Key Reading Configuration File – Binance Python Trading Bot: Syntax Error: (Unicode error)
Here is an article that addresses your issue:
Configuration File for Reading Ethereum API Key: Step by Step Guide for Beginners
Greeting! Congratulations on starting your coding journey, especially with trading bots. As a beginner, setting up and installing the necessary libraries and configurations for your bot can be overwhelming. In this article, we will walk you through how to read an Ethereum API key from a configuration file using Python.
Why are you struggling?
You get a SyntaxError: (unicode error)' message, indicating that there is a problem with the syntax of the code. Don't worry; It's easy to solve! In this article, we will focus on setting up the correct configuration and resolving the syntax error.
Prerequisites
Before diving into the instructions, make sure you have:
- Python installed on your computer
- Test Ethereum API key from Binance (or any other Ethereum API)
- Basic understanding of Python programming
Step 1: Select the location of the configuration file
Create a new file calledconfig.jsonin the same directory as your trading bot script. This file will store your API key.
Example config.json:
{
"api_key": "YOUR_API_KEY_HERE",
"api_secret_key": "YOUR_API_SECRET_KEY_HERE"
}
Replace YOUR_API_KEY_HEREand
YOUR_API_SECRET_KEY_HEREwith your actual Binance API keys.
Step 2: Install the required libraries
You will need to install the following libraries:
- requests
: for making HTTP requests
- json
: for parsing JSON data
Run the following commands in your terminal:
pip installation requirements
pip install json
Step 3: Read the API key from the configuration file
Open your config.jsonfile and add your Binance API key:
{
"api_key": "YOUR_API_KEY_HERE",
"api_secret_key": "YOUR_API_SECRET_KEY_HERE"
}
Save the changes to your configuration file.
Step 4: Update your trading bot script
Modify your trading bot script (eg trading_bot.py`) to read the API key from the configuration file:
import requirements
def get_api_keys():
api_key = None
try:
Use configuration file to get API keys
with open('config.json', 'r') as f:
data = json.load(f)
api_key = data['api_key']
return api_key
except for exceptions like e:
print(f"Error reading API key from configuration file: {e}")
Get an API key and use it to submit a request
api_key = get_api_keys()
print(api_key)
Output: YOUR_API_KEY_HERE
Make a request using the API key
url = "
headers = {'api_key': api_key, 'api_secret_key': 'YOUR_API_SECRET_KEY_HERE'}
response = requests.get(url, headers=headers)
print(response.json())
Output: JSON data from Binance API
Step 5: Start Your Trading Robot
Finally, run your trading bot script using Python:
python trading_bot.py
This should connect to the Ethereum API test and print your API key.
That’s it! You have successfully read the Ethereum API key from the configuration file and used it in your trading bot. Don’t forget to update your code with your own Binance API keys when you’re ready for production use. Good luck and happy coding!
