What equipment cannot be used for programming? Unprogrammable device

During the programming process, we usually use various input devices to interact with the computer, such as keyboard, mouse, touch screen, etc. However, not all devices are suitable for programming, and some devices may not be suitable for programming tasks due to their characteristics or limitations. Here are some devices that are not suitable for programming.

1. Printer: A printer is an output device used to print electronic documents into paper files. Although a printer can print out program code, it is not an input device suitable for programming. It lacks the ability to interact with the computer in real time and cannot provide real-time input and feedback.

# 示例代码
print("Hello, World!")

2. Camera: A camera is typically used to capture images or videos and transfer them to a computer. While a camera can be used for programming tasks such as image processing and computer vision, it cannot be used directly as an input device for programming. The main function of the camera is to capture images, not to receive user input.

# 示例代码
import cv2

# 打开摄像头
cap = cv2.VideoCapture
