How to Create a Cryptocurrency Converter in Python

In this article, you’ll learn how to create a cryptocurrency converter using Python. A cryptocurrency converter is a tool that allows you to convert between different cryptocurrencies and traditional fiat currencies like US Dollars, Euros, and Pounds.

It’s a handy tool for people who use digital currencies, whether they’re investing, buying things online, or just curious about how much their cryptocurrency is worth in regular money.

Building the Cryptocurrency Converter

First of all, I will create a new file called “cryptoconverter.py” using nano text editor in the terminal.

nano cryptoconverter.py

Add the following code:

import requests
import tkinter as tk
from tkinter import messagebox
class CryptoConverter:
def __init__(self, master):
self.master = master
self.master.title("Crypto Converter")
self.master.geometry("400x200")
self.label1 = tk.Label(self.master, text="Amount:")
self.label1.grid(row=0, column=0, padx=10, pady=10)
self.amount_entry = tk.Entry(self.master)
self.amount_entry.grid(row=0, column=1, padx=10, pady=10)
self.label2 = tk.Label(self.master, text="From:")
self.label2.grid(row=1, column=0, padx=10, pady=10)
self.from_currency_var = tk.StringVar()
self.from_currency_var.set("BTC")
self.from_currency_dropdown = tk.OptionMenu(self.master, self.from_currency_var, "BTC", "ETH", "LTC")
self.from_currency_dropdown.grid(row=1, column=1, padx=10, pady=10)
self.label3 = tk.Label(self.master, text="To:")
self.label3.grid(row=2, column=0, padx=10, pady=10)
self.to_currency_var = tk.StringVar()
self.to_currency_var.set("USD")
self.to_currency_dropdown = tk.OptionMenu(self.master, self.to_currency_var, "USD", "EUR", "GBP")
self.to_currency_dropdown.grid(row=2, column=1, padx=10, pady=10)
self.convert_button = tk.Button(self.master, text="Convert", command=self.convert)
self.convert_button.grid(row=3, columnspan=2, padx=10, pady=10)
def convert(self):
try:
amount = float(self.amount_entry.get())…
