Lesson 14: Python Refresher — Integrating Python with Technologies

One way to integrate technologies is by using Python's built-in modules or external libraries. For example, import the math module to access math functions:

import math
print(math.sqrt(16))  # prints 4.0

You can install many packages (like requests, numpy, etc.) for additional features. For instance, using requests you could fetch data from a web API:

import requests
response = requests.get("https://api.example.com/data")
print(response.json())

(This code requires the requests library and internet access; just for illustration.) Integrating such libraries extends Python beyond basic arithmetic and text handling, allowing database access, web requests, or data science tasks.

Interactive applications often have graphical interfaces. Python's tkinter is a basic GUI library. For example:

import tkinter as tk

window = tk.Tk()
window.title("Sample App")
label = tk.Label(window, text="Hello GUI!")
label.pack()
window.mainloop()

This creates a small window with the text "Hello GUI!". Learning a full GUI framework is advanced, but knowing it exists shows how programming can create desktop apps. The mainloop() call is an event loop that waits for user interaction (clicks, etc.). In exams, you might only be asked conceptual questions about event-driven programming (e.g. "what is an event loop?"), not full GUI code.
