☁️ Python Command-Line Weather App

A concise and functional application built entirely in Python to fetch and display real-time weather data for any major city worldwide.

This project demonstrates core programming concepts including API integration, data parsing (JSON), and error handling, making it a complete portfolio piece.

🚀 Getting Started

Follow these steps to run the application on your local machine.

1. Prerequisites

You must have Python 3 installed and the requests library.

# Install the necessary Python library
pip install requests

2. Set up the API Key

You need a free API key from OpenWeatherMap:

1. Sign up for an account at OpenWeatherMap.

2. Navigate to the "My API Keys" section to find your key.

3. Open the weather_app.py file and replace the placeholder text with your actual key:

   # IMPORTANT: Replace 'YOUR_API_KEY' with your actual API key!
   API_KEY = "YOUR_API_KEY"

3. Run the App

Execute the Python script from your terminal:

python weather_app.py

The application will launch and prompt you to enter a city name:

Enter city name (or 'exit' to quit): Paris, France
