How to get data from OpenWeather API
Getting data from weather APIs

Building a Simple Weather App with Python and OpenWeatherMap API


Have you ever wanted to create a simple weather app that provides real-time weather information? In this tutorial, we’ll guide you through building a basic weather app using Python and the OpenWeatherMap API. By the end of this tutorial, you’ll be able to retrieve and display weather data for a given location.


Before we begin, make sure you have Python installed on your machine. You’ll also need to sign up for a free OpenWeatherMap API key at

Step 1: Setting Up the Environment

Create a new Python file for your weather app project. Let’s import the required libraries and set up your OpenWeatherMap API key:

import requests

API_KEY = ‘your_api_key_here’


Step 2: Retrieving Weather Data

We’ll use the OpenWeatherMap API to fetch weather data for a specific location. Replace 'City, Country' with the location you’re interested in:

location = 'City, Country'
url = f'{location}&appid={API_KEY}'
response = requests.get(url)
data = response.json()

Step 3: Extracting and Displaying Weather Information

Now that we have the weather data, let’s extract and display relevant information:

temperature = data['main']['temp']
description = data['weather'][0]['description']
humidity = data['main']['humidity']
print(f'Temperature: {temperature} K')
print(f'Description: {description}')
print(f'Humidity: {humidity}%')

Step 4: Converting Temperature Units

To provide a more user-friendly temperature display, let’s convert the temperature from Kelvin to Celsius:

temperature_celsius = temperature - 273.15
print(f'Temperature: {temperature_celsius:.2f} °C')

Step 5: Error Handling

Handle potential errors, such as invalid locations or API issues:

if response.status_code == 200:
# Display weather information
print('Error fetching weather data. Please check your location and API key.')


Congratulations! You’ve successfully built a simple weather app that fetches and displays real-time weather data using Python and the OpenWeatherMap API. With this basic foundation, you can expand the app by adding more features like forecasts, graphical representations, and user input for location. Remember to keep your API key secure and adhere to usage limits. Now you have a practical application that showcases your coding skills and keeps you informed about the weather conditions. Happy coding and weather monitoring! 🌦🌡🐍
