5 Fun Python Projects: Flag, ASCII Art, Tetris, Shooter & Face Detection

This article integrates several entertaining Python code examples to spark interest and enhance programming skills.

1. Drawing a Flag with Turtle

The code for drawing a national flag using the turtle module is shown below.

Running the script dynamically renders the flag, as illustrated in the following screenshots.

To install the required third‑party package, use pip from the Anaconda2\Scripts directory as shown.

2. Converting Images to ASCII Art

The following image contains the Python code that transforms a picture into a text‑based representation.

Running the script produces the displayed ASCII art results.

Note: Viewing the original image within a plain text editor is limited because the ASCII output uses a small font size.

3. Building a Tetris Clone

The Tetris implementation relies on a configuration file elsfk.cfg that defines the shapes of the tetrominoes; the file format is documented in the code comments.

Because the source code exceeds 500 lines and may not display correctly on mobile devices, a full version is linked externally.

Running the program yields the following screenshots.

Installation requires pip install pygame, and horizontal movement currently advances two steps at a time.

4. Creating a Simple Plane Shooter

The development steps are: display the background, render the aircraft, and animate its movement.

Resulting screenshots are shown below.

5. 25‑Line Face Detection with OpenCV

First, install OpenCV and copy cv2.pyd into the Python site‑packages directory.

Download the source code as shown.

Run the script from the command line:

C:\>cd C:\Users\yxz15\Desktop\FaceDetect-master
python face_detect.py bbbb.jpg haarcascade_frontalface_default.xml

The execution detects all faces, as demonstrated in the following output images.

The source code of face_detect.py is displayed in the image below.
