Weather API Integration Tutorial Series for Kivy & KivyMD Weather App | Part 5 by Novfensec Inc.

Welcome to Part 5 of our Kivy & KivyMD Weather App Tutorial Series by Novfensec Inc.! In this tutorial, we will be focusing on integrating a Weather API into our app to fetch real-time weather data. By the end of this tutorial, you will be able to display current weather information in your Kivy app.

Step 1: Sign up for a Weather API

The first step is to sign up for a Weather API service. There are many free and paid options available, such as OpenWeatherMap, Weatherbit, and AccuWeather. For this tutorial, we will be using the OpenWeatherMap API. Sign up for a free account and obtain your API key.

Step 2: Install Requests library

To make HTTP requests to the Weather API, we will need to install the Requests library. Open your terminal or command prompt and run the following command:

pip install requests

Step 3: Create a Weather API Service class

Next, we will create a Python class that will handle the communication with the Weather API. Create a new file named weather_api_service.py and add the following code:

import requests

class WeatherAPIService:
    def __init__(self, api_key):
        self.api_key = api_key
        self.base_url = "http://api.openweathermap.org/data/2.5/weather"

    def get_weather_data(self, city):
        params = {
            "q": city,
            "appid": self.api_key,
            "units": "metric"
        }

        response = requests.get(self.base_url, params=params)
        data = response.json()

        return data

Step 4: Display weather data in your Kivy app

Now that we have our Weather API service ready, we can integrate it into our Kivy app. Modify your main.py file to include the Weather API service and display the weather data on the app screen. Here is a basic example of how you can achieve this:

from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.label import Label
from weather_api_service import WeatherAPIService

class WeatherApp(BoxLayout):
    def __init__(self):
        super(WeatherApp, self).__init__()

        api_key = "YOUR_API_KEY_HERE"
        weather_service = WeatherAPIService(api_key)

        data = weather_service.get_weather_data("London")

        temperature = data['main']['temp']
        description = data['weather'][0]['description']

        self.orientation = "vertical"

        self.add_widget(Label(text=f"Temperature: {temperature}°C"))
        self.add_widget(Label(text=f"Description: {description}"))

class MainApp(App):
    def build(self):
        return WeatherApp()

if __name__ == '__main__':
    MainApp().run()

Replace YOUR_API_KEY_HERE with your actual OpenWeatherMap API key. Run your Kivy app and you should see the current temperature and weather description for the city you specified.

Congratulations! You have successfully integrated a Weather API into your Kivy app. Stay tuned for the next part of our tutorial series where we will be adding more features to our Weather app. Thank you for following along with Novfensec Inc.!
