🌤️ Weather API Integration with Python

This tutorial demonstrates how to fetch and display real-time weather information using Python and the OpenWeatherMap API.

📦 Requirements

• Python 3.x
• requests library (pip install requests)
• Free API key from OpenWeatherMap

🧪 Script Overview

The script prompts the user for a city name, builds a query URL using the OpenWeatherMap API, sends a GET request, and displays temperature, humidity, wind speed, and a weather description.

📤 Example Output

Enter a city: San Diego
Requesting: http://api.openweathermap.org/data/2.5/weather?q=San Diego&appid=XXXX&units=imperial
Weather in San Diego: overcast clouds
Temperature: 64.67°F
Humidity: 84%
Wind Speed: 4.61 mph

🧾 Full Code

import requests

# Your API key
API_KEY = "your_api_key_here"

# Create city input prompt
city = input("Enter a city: ")

url = f"http://api.openweathermap.org/data/2.5/weather?q={city}&appid={API_KEY}&units=imperial"

# Send the GET request
response = requests.get(url)

print(f"Requesting: {url}")

# Check if the request was successful
if response.status_code == 200:
    data = response.json()

    # Extract useful info
    weather = data["weather"][0]["description"]
    temperature = data["main"]["temp"]
    humidity = data["main"]["humidity"]
    wind_speed = data["wind"]["speed"]

    # Print it out nicely
    print(f"Weather in {city}: {weather}")
    print(f"Temperature: {temperature}°F")
    print(f"Humidity: {humidity}%")
    print(f"Wind Speed: {wind_speed} mph")
else:
    print(f"Failed to get data: {response.status_code} - {response.text}")

🔍 How It Works

• User enters a city name via input prompt
• Script builds and sends an API request to OpenWeatherMap
• JSON response is parsed and weather data is extracted
• Data is printed to the terminal in a human-readable format
