Creating a Weather Forecasting Application with Python

In this post, we'll be going over how to create a simple weather forecasting application using Python. We'll be utilizing the OpenWeatherMap API for this task.

Installing Necessary Libraries

First, we need to install the necessary library. In this post, we will use the requests library. Execute the following command to install it.

pip install requests

Acquiring the OpenWeatherMap API

To use the OpenWeatherMap API, we need to first get the API key. You can sign up on the OpenWeatherMap website and receive the API key. You can apply the acquired API key to the code as follows.

API_KEY = "your_api_key_here"

Obtaining Weather Data

With the API key obtained, we can now fetch weather data for a specific city. Here's how to get the current weather data for a specific city using the OpenWeatherMap API.

import requests

BASE_URL = "http://api.openweathermap.org/data/2.5/weather?"
CITY = "your_city_here"
API_KEY = "your_openweathermap_api_key_here"
URL = BASE_URL + "q=" + CITY + "&appid=" + API_KEY

response = requests.get(URL)
data = response.json()

if data["cod"] != "404":
    main = data["main"]
    weather_desc = data["weather"][0]["description"]
    print("Temperature :" + str(main["temp"]))
    print("Weather description :" + weather_desc)
else:
    print("City Not Found!")

Conclusion

That's it! You've just built a simple weather forecasting application using Python and the OpenWeatherMap API. This is a great starting point and you can expand on this by incorporating more features like forecasts for the coming days, different cities, etc. Happy coding!
