Crypto Price Checker

Overview

This project is a cryptocurrency price checking application that fetches data from CoinMarketCap for various cryptocurrencies. It extracts and displays key information such as price, 24-hour trading volume, and percentage changes over different time periods.

User Interface

User_interface

Settings_menu

Files

  • crypto_names.json: Contains a list of cryptocurrency names to monitor.
  • current_holdings.json: Placeholder for storing user's current holdings of cryptocurrencies.
  • settings.json: Configuration file for customizing the display format of cryptocurrency data.

Python Scripts

  • user_interface.py: Runs the main application. It fetches cryptocurrency prices from the web and logs them according to settings specified in settings.json. Additional information displayed includes 24-hour trading volume, price, 24 hours, 7 days, and 30 days.

  • new_coin.py: Allows users to update crypto_names.json by adding new cryptocurrency names. It ensures that duplicate names are not added to the file.

  • get_data.py: Retrieves cryptocurrency data from CoinMarketCap using web scraping techniques. It extracts price, 24-hour trading volume, and percentage changes over 24 hours, 7 days, and 30 days. Ensure the script is configured to match the structure of the actual website providing cryptocurrency data.

Usage

  1. Setup: Ensure crypto_names.json, current_holdings.json, and settings.json are correctly populated with initial data.

  2. Run Application: Execute user_interface.py to start the application. It will fetch data from CoinMarketCap and log it based on the settings configured in settings.json.

Adding New Cryptocurrencies

To add new cryptocurrency names to crypto_names.json, use new_coin.py. This script ensures that each cryptocurrency name is unique to avoid duplication in the list.

Adding and Removing Cryptocurrencies in the App

In the application (user_interface.py), you can dynamically add or remove cryptocurrencies using a user interface. Here's how it works:

  1. Adding Cryptocurrencies:

    • Type the cryptocurrency name into the first entry field.
    • Enter the amount in the second entry field.
    • Click on the "Add" button to add the cryptocurrency with the specified amount to your holdings.

  2. Removing Cryptocurrencies:

    • Similarly, type the cryptocurrency name into the first entry field.
    • Enter the amount in the second entry field (typically as a negative value to indicate removal).
    • Click on the "Remove" button to adjust your holdings by removing the specified amount of the cryptocurrency.

These features allow for easy management and updating of your cryptocurrency holdings directly within the application interface.

Dependencies

  • Python 3.11

Installed Packages and Versions

  • customtkinter: 5.2.2
  • requests: 2.31.0
  • bs4 (Beautiful Soup): 0.0.2

These are the specific versions of Python and the libraries used in the application. Ensure that you have these versions installed or compatible versions when running the application.

Notes

  • Ensure internet connectivity for fetching live cryptocurrency data from CoinMarketCap.
  • Use new_coin.py and get_data.py responsibly and in compliance with the terms of service of CoinMarketCap or any other website from which data is fetched.
