Weather API Integration in python

To integrate a weather API in Python, you can use a third-party library like requests and json to make API requests and handle the response data. Here is an example of how to integrate the OpenWeatherMap API:

1. Sign up for a free OpenWeatherMap API key on their website.

2. Install the requests library using pip:

    pip install requests
   

3. Import the request and json modules

    import requests
    import json
   

4. Define the API endpoint URL and API key:

    api_endpoint = 'http://api.openweathermap.org/data/2.5/weather' 
    api_key = 'your_api_key'
   

5. Define the parameters for the API request:

    params = { 
    'q': 'city_name', 
    'units': 'metric', 
    'appid': api_key 
    }
   

   The q parameter is the city name for which you want to retrieve the weather data. The units parameter sets the unit of measurement to Celsius. The appid parameter is the API key.

6. Make the API request using the requests.get() method:

    response = requests.get(api_endpoint, params=params)
   

7. Check the status code of the response to make sure the API request was successful:

    if response.status_code == 200: 
    data = response.json() # do something with the data 
    else: 
    print('Error:', response.status_code)
   

8. If the status code is 200, parse the JSON data from the response using the json() method, and then use the data as needed. For example, to retrieve the temperature:

    temperature = data['main']['temp'] 
    print('Temperature:', temperature)
   

   That's it! You can now use this example as a starting point for integrating other weather APIs in Python.
