Prerequisites

Before we dive into building the video rental system, make sure you have Python installed on your computer. Additionally, ensure that Tkinter is available, as it's commonly included with Python distributions.

Code and Explanations

Let's start by creating the Python code for our video rental system. We'll provide explanations for each code block before moving on to the next.

Importing Necessary Modules

```python # Import the required modules import tkinter as tk from tkinter import messagebox ```

Explanation:

• We begin by importing the necessary modules. `tkinter` is used for creating the GUI, and `messagebox` is used for displaying messages to the user.

Creating the Video Rental System Class

```python # Create a class for the Video Rental System class VideoRentalSystem: def __init__(self, root): self.root = root self.root.title("Video Rental System") # Initialize data structures to store video information self.videos = {"Movie1": 5, "Movie2": 3, "Movie3": 7} self.rented_videos = {} ```

Explanation:

• We define a `VideoRentalSystem` class to encapsulate the video rental system's functionality.
• Inside the class constructor `__init__`, we set the window title and initialize data structures to store video information.

Creating GUI Elements

```python # Create labels and entry fields self.label_title = tk.Label(root, text="Title:") self.label_title.pack() self.entry_title = tk.Entry(root) self.entry_title.pack() self.label_available = tk.Label(root, text="Available:") self.label_available.pack() self.label_available_count = tk.Label(root, text="") self.label_available_count.pack() ```

Explanation:

• We create labels and entry fields for user input.
• `self.label_title` and `self.entry_title` are used for entering the title of the video.
• `self.label_available` and `self.label_available_count` display the label and available count of the selected video.

Creating Buttons

```python # Create buttons self.rent_button = tk.Button(root, text="Rent", command=self.rent_video) self.rent_button.pack() self.return_button = tk.Button(root, text="Return", command=self.return_video) self.return_button.pack() ```

Explanation:

• We create "Rent" and "Return" buttons to trigger actions.
• `self.rent_button` and `self.return_button` execute the `rent_video` and `return_video` methods when clicked.

Updating Available Video Count

```python # Update the available count label self.update_available_count() ```

Explanation:

• We call the `update_available_count` method to initialize the available video count label.

The code provided so far sets up the initial structure of our video rental system GUI. In the next sections, we'll define the methods for renting and returning videos and complete the application.

Conclusion

In conclusion, this guide has provided you with a solid foundation for developing a video rental system with a user-friendly GUI using Python and Tkinter. By following the code and explanations, you've learned essential concepts in GUI development, data management, and user interaction. With the knowledge gained here, you're well-equipped to expand and customize your video rental system, add advanced features, and embark on further Python GUI development projects. Happy coding, and may your programming journey continue to thrive!
