Create a modern GUI Weather Update App using Custom Tkinter Python (Part 1)

Python is a powerful programming language that is widely used for developing desktop applications. Tkinter is a popular library for creating graphical user interfaces (GUI) in Python. In this tutorial, we will create a modern GUI weather update app using custom Tkinter in Python.

Setting up the environment

Before we start building the weather update app, we need to make sure that we have Python and Tkinter installed on our system. Python comes pre-installed on most operating systems, but if it is not installed on your system, you can download it from the official Python website. Tkinter is also included with Python, so you don’t need to install it separately.

Creating the main window

Once we have Python and Tkinter installed, we can start creating our weather update app. The first step is to create the main window of the app using the Tkinter library. We can use the following code to create a simple window:

	import tkinter as tk

	root = tk.Tk()
	root.title("Weather Update App")
	root.geometry("400x300")

	root.mainloop()
	

Adding widgets to the window

Now that we have created the main window, we can start adding widgets to it. Widgets are the building blocks of the GUI, and they can be used to display text, images, buttons, and other interactive elements. In our weather update app, we will use labels to display the current weather information, and a button to refresh the weather data. We can use the following code to add these widgets to the main window:

	label = tk.Label(root, text="Current Weather: Sunny")
	label.pack()

	button = tk.Button(root, text="Refresh", command=refresh_weather)
	button.pack()
	

Fetching weather data

Now that we have added the necessary widgets to the main window, we need to fetch the current weather data from an online source. We can use the requests library to make a GET request to a weather API and retrieve the weather information. Here’s how we can do that:

	import requests

	def refresh_weather():
	    response = requests.get("https://api.openweathermap.org/data/2.5/weather?q=London&appid=YOUR_API_KEY")
	    data = response.json()
	    weather = data["weather"][0]["main"]
	    label.config(text="Current Weather: " + weather)
	

With the above code, we can fetch the current weather information for a specific location and display it in the app’s main window. In the next part of this tutorial, we will continue to enhance our weather update app by adding more features and customizing the GUI.
