Weather App Source Code

import requests
import json

# Function to get weather data
def get_weather(city, api_key):
    # Base URL of the OpenWeatherMap API
    url = f'http://api.openweathermap.org/data/2.5/weather?q={city}&appid={api_key}&units=metric'
    
    # Sending GET request to the API
    response = requests.get(url)
    
    # If the request was successful
    if response.status_code == 200:
        data = response.json()
        
        # Extracting useful information
        city_name = data['name']
        country = data['sys']['country']
        temperature = data['main']['temp']
        humidity = data['main']['humidity']
        weather_desc = data['weather'][0]['description']
        wind_speed = data['wind']['speed']
        
        # Display the weather information
        print(f"Weather in {city_name}, {country}:")
        print(f"Temperature: {temperature}°C")
        print(f"Weather: {weather_desc.capitalize()}")
        print(f"Humidity: {humidity}%")
        print(f"Wind Speed: {wind_speed} m/s")
    else:
        print(f"City {city} not found or an error occurred!")

# Main function
def main():
    # Get your OpenWeatherMap API key (sign up at https://openweathermap.org/)
    api_key = 'YOUR_API_KEY'  # Replace with your own API key

# Get city input from user
    city = input("Enter city name: ")

# Get the weather data
    get_weather(city, api_key)

if __name__ == "__main__":
    main()

Steps to Run the Weather App

1. Get an API Key: Sign up on OpenWeatherMap and generate an API key.

2. Install Requests Library: In your terminal, run:
3. Save the Code: Save the code in a .py file, for example, weather_app.py.

4. Replace the API Key: Replace 'YOUR_API_KEY' in the script with your actual API key from OpenWeatherMap.

5. Run the Program: In your terminal or command prompt, navigate to the folder where your script is located and run:
6. Enter a City: The app will prompt you to enter a city name, and it will fetch and display the weather information for that city.

Example Output

You can modify the script to display the weather in different units (e.g., Kelvin or Fahrenheit) by changing the units parameter in the URL.

You could also improve the user interface, add error handling, or even create a graphical user interface (GUI) using libraries like Tkinter or PyQt.
