Build a temperature converter GUI

Here’s a simple Temperature Converter GUI using Python and the tkinter library:

python
CopyEdit
import tkinter as tk
from tkinter import ttk

def convert_temperature():
    try:
        temp = float(entry_temp.get())
        if temp_type.get() == "Celsius to Fahrenheit":
            result = (temp * 9/5) + 32
            result_label.config(text=f"{result:.2f} °F")
        else:
            result = (temp - 32) * 5/9
            result_label.config(text=f"{result:.2f} °C")
    except ValueError:
        result_label.config(text="Invalid input")

# Create main window
root = tk.Tk()
root.title("Temperature Converter")
root.geometry("300x200")
root.resizable(False, False)

# Input label and entry
entry_label = ttk.Label(root, text="Enter Temperature:")
entry_label.pack(pady=5)

entry_temp = ttk.Entry(root, width=20)
entry_temp.pack(pady=5)

# Dropdown for conversion type
temp_type = tk.StringVar(value="Celsius to Fahrenheit")
conversion_menu = ttk.Combobox(root, textvariable=temp_type, values=["Celsius to Fahrenheit", "Fahrenheit to Celsius"], state="readonly")
conversion_menu.pack(pady=5)

# Convert button
convert_button = ttk.Button(root, text="Convert", command=convert_temperature)
convert_button.pack(pady=10)

# Result display
result_label = ttk.Label(root, text="", font=("Helvetica", 14))
result_label.pack(pady=10)

# Start the GUI event loop
root.mainloop()

Features:

• Converts between Celsius and Fahrenheit.

• Validates numeric input.

• Uses ttk for a clean look.

Requirements:

This runs with any standard Python installation (Python 3.x), as tkinter is included by default.
