Building a Weather App with Python and Streamlit

In this tutorial, we will create a simple weather app using Python and Streamlit. The app will fetch weather data from the OpenWeatherMap API and display it in a user-friendly format.

Step 1: Install Required Libraries

To begin, make sure you have Streamlit installed. If not, you can install it using the following command:

pip install streamlit

Step 2: Obtain an API Key from OpenWeatherMap

Before we proceed, you need an API key from OpenWeatherMap to access their weather data. Here’s how to get one:

1. Go to the OpenWeatherMap website: https://home.openweathermap.org/users/sign_up.
2. Sign up for a new account.
3. After signing up, log in to your account.
4. Once logged in, go to the API Keys tab.
5. Generate a new API key and make sure to keep it safe.

Step 3: Create the Weather App

Now, let’s create the weather app. Create a new Python script named weather_app.py and follow the steps below:

import streamlit as st
import requests

Here, we import the necessary libraries. streamlit is used to create the web app interface, and requests is used to make HTTP requests to the OpenWeatherMap API. Define a function to get weather data from the…
