Create a Weather App using API in Python

Hello Coders, welcome to the CodeWithRandom blog!
Are you curious about how to build your own weather app in Python? In this tutorial, we are creating a Weather App using API in Python. If you study Python and want to create a project, then this is a very interesting project, perfect for you!

We will use a weather API (like WeatherAPI, fetch live weather data, and display it in the terminal. No fancy GUI required – just logic, API calls, and Python magic. Today, we are going to build a Weather App using Python and a free Weather API. This project is beginner-friendly and will help you learn how to interact with APIs in Python. No GUI, no complexities – just simple Python + API magic.

This project is perfect for beginners who want to practice working with APIs, JSON data, and Python libraries. You only need some basic knowledge of Python to get started.

Let’s start :

What Will You Learn in the Weather project?

How to use a public API in Python
How to make HTTP requests using requests library
How to parse and display JSON data
How to structure a basic CLI-based app
Importance of API keys and documentation

Why This Weather Project?

This is one of the most searched and trending beginner projects in Python right now. Many new developers want to learn how to integrate APIs in real projects, and this is the perfect place to start.

This app can be further upgraded with a GUI, voice input, or even converted to a web app – so this is an excellent base project.

What is an API?

API (Application Programming Interface) is a way for one piece of software to interact with another. In this project, we’ll use the free and powerful WeatherAPI to fetch weather details for any city.

Tools and Technologies

Python 3.6+
requests module
WeatherAPI (Sign up for a free key)
Terminal / VS Code / Command Line

Install Required Module

pip install requests

pip install requests

Get Your API Key

Go to weatherapi.com, sign up for a free account, and copy your API key. We’ll need it to authenticate requests.

Python Weather App Code

Showing temperature in both Celsius and Fahrenheit
Displaying feels like temperature
Showing local time of the city
Adding error handling for invalid inputs / network issues
Asking user if they want to check multiple cities in one run

What’s Happening in the Code?

We are used requests.get() to calling the API.
The response is in JSON format – we parse it using .json().
The weather details are printed in a clean format.
If an error occurs (like the wrong city), it’s handled.

Building a Weather App using API in Python is a perfect project to understand how real-world apps use data from external sources. It’s beginner-friendly, scalable, and widely searched by learners and tech enthusiasts. We hope you enjoyed building this with us!

FAQs

Q. Is this Weather API free?
Yes, for basic usage and personal projects, it’s completely free.

Q. Can I get the weather by coordinates?
Yes! Just replace the city name with the lat, long in the q parameter.

Q. Is it possible to get the weather forecast for the next 3 days?
Yes, just use the forecast.json endpoint instead of current.json.
