Code Example

Here’s a basic code example in Python using the requests library to fetch weather data from a hypothetical free weather API:

import requests

def get_weather(city):
    url = f"https://api.exampleweather.com/weather?q={city}"
    response = requests.get(url)

    if response.status_code == 200:
        data = response.json()
        print(f"Weather in {city}: {data['weather'][0]['description']}, Temperature: {data['main']['temp']}°C")
    else:
        print("Error fetching weather data.")

get_weather("London")
