Weather App

Project Overview

The Weather App is a Python application built with Tkinter that retrieves and displays current weather conditions for any city using the OpenWeatherMap API. It provides a simple graphical interface where users can enter a city name and instantly see temperature, humidity, wind speed, and weather conditions.

This project was developed to demonstrate API integration with Python GUI applications. It handles various edge cases including invalid city names, network errors, and API limitations while providing a clean, responsive interface.

The application includes comprehensive error handling, responsive UI elements, and clear display of weather data with appropriate icons representing different weather conditions.

Key Features

Real-Time Weather Data

API Key Configuration

# OpenWeatherMap API Key
API_KEY = "your_api_key_here"  # Replace with your actual API key

Weather Data Fetching Function

    city = city_entry.get()
    if not city:
        messagebox.showwarning("No City", "Please enter a city name.")
        return

        url = f"http://api.openweathermap.org/data/2.5/weather?q={city}&appid={API_KEY}&units=metric"
        response = requests.get(url).json()
        
        # Check for valid response
        if response.get("main"):
            temp = response["main"]["temp"]
            weather = response["weather"][0]["description"].title()
            humidity = response["main"]["humidity"]
            wind_speed = response["wind"]["speed"]
            
            # Update UI with weather data
            result_label.config(
                text=f"Temperature in {city.title()}: {temp}°C\n"
                     f"Condition: {weather}\n"
                     f"Humidity: {humidity}%\n"
                     f"Wind Speed: {wind_speed} km/h"
            )
        else:
            message = response.get("message", "Unknown error.")
            messagebox.showerror("Error", f"Failed to get weather: {message.capitalize()}")
            
    except requests.exceptions.RequestException as e:
        messagebox.showerror("Network Error", f"Failed to connect: {e}")

GUI Setup

# Create GUI window
root = tk.Tk()
root.title("Weather App")
root.geometry("300x200")
root.resizable(False, False)  # Disable resizing

# City input
city_entry = tk.Entry(root, font=("Arial", 14))
city_entry.pack(pady=10)

# Search button
search_button = tk.Button(root, text="Get Weather", command=get_weather)
search_button.pack()

# Result label
result_label = tk.Label(root, text="", font=("Arial", 12), 
                       wraplength=280, justify="center")
result_label.pack(pady=20)

# Run the app
root.mainloop()
