Achieving Dynamic Console Printing in Python for Your Trading Bot

If you're new to programming in Python, you may find yourself facing a few common challenges as you build your projects. One such challenge is displaying updated information in your console without cluttering it with repeated print statements. Particularly, if you're working on a bot that displays trading results, such as your Ethereum balances, you'll want your output to remain clear and easily readable while continuously updating. In this post, we'll explore how to achieve dynamic console printing in Python, so your results update in real-time on the same lines.

The Challenge: Updating Console Output

In the code you provided, you're trying to display trading results including:

Coin type

Current balance

Starting balance

Total profit

Total equity

When run repeatedly, each output appears as a new block, which isn’t efficient for monitoring your results. The goal is to update the previous output in place rather than printing new lines for every update.

Example Output Issue

Currently, the output in your terminal looks like this when you print each result:

This creates clutter in the console and makes it difficult to track the changing values.

A Solution: Clearing the Console for Updates

One effective way to deal with this issue is to clear the console before rendering the new results. Although Python’s print function doesn't allow you to overwrite already printed lines directly, you can simulate this by clearing the console.

Step-by-step Instructions

Clear the Console:

You can clear the console by printing multiple new lines. Here’s a simple way to do it:

This effectively pushes any prior output off the console so you can see only the latest information.

Update Your Function:

Incorporate this clear command in your eth_results function to achieve a clean display:

Implement a Loop:

As you already set up, you can run this function in an infinite loop with a sleep interval of your choice:

By adopting this method, every time eth_results() is invoked, the previous output will be cleared, and the updated results will be presented clearly.

Bonus: Consider Future Improvements

While this approach works effectively for your immediate needs, you might want to explore more advanced techniques in the future such as using libraries like curses for creating a text-based user interface, or even integrating real-time updates in a web application instead of terminal output.

Conclusion

In summary, dynamically updating your trading results in Python without cluttering your console is achievable through simple techniques of displaying new lines to clear previous output. As you grow more comfortable with Python, you'll find more sophisticated methods to enhance your application's functionality. Happy coding!
