Python Tkinter Application for Currency Exchange

Currency exchange apps have become increasingly popular as more people need to convert currencies for various purposes such as travel or business. In this tutorial, we will create a Currency Exchange App using Python Tkinter, a standard GUI toolkit for Python.

To get started, you will need to have Python installed on your computer. You can download Python from the official website and install it following the instructions provided.

Once Python is installed, you can install Tkinter using the following command:

pip install tk

After installing Tkinter, you can create a new Python file and import the necessary modules:

import tkinter as tk
from forex_python.converter import CurrencyRates

We will also use the forex-python library to get the currency exchange rates. You can install this library using the following command:

pip install forex-python

Now, let’s create the main window of our Currency Exchange App:

root = tk.Tk()
root.title("Currency Exchange App")

Next, we will create two Label widgets to display the instructions and the result of the currency conversion:

instruction_label = tk.Label(root, text="Enter amount and select currencies to convert:")
instruction_label.pack()

result_label = tk.Label(root, text="")
result_label.pack()

Then, we will create two Entry widgets to allow the user to enter the amount to convert and select the currencies to convert:

amount_entry = tk.Entry(root)
amount_entry.pack()

from_currency_entry = tk.Entry(root)
from_currency_entry.pack()

to_currency_entry = tk.Entry(root)
to_currency_entry.pack()

We will also create a Button widget that will trigger the currency conversion when clicked:

def convert_currency():
    amount = float(amount_entry.get())
    from_currency = from_currency_entry.get()
    to_currency = to_currency_entry.get()
    c = CurrencyRates()
    result = c.convert(from_currency, to_currency, amount)
    result_label.config(text=f"{amount} {from_currency} = {result} {to_currency}")

convert_button = tk.Button(root, text="Convert", command=convert_currency)
convert_button.pack()

Finally, we will run the main event loop to display the Currency Exchange App:

root.mainloop()

That’s it! You have created a simple Currency Exchange App using Python Tkinter. You can further enhance the app by adding error handling, more currency options, or a graph to visualize the exchange rates.

I hope you found this tutorial helpful in creating your own Currency Exchange App. If you have any questions or need further assistance, feel free to ask. Happy coding!
