As we plan our AI robot to play Connect-4, we have decided that Python would be a good programming language for the job, as it is widely used for many of the tasks we will need to do:

• Computer vision
• Artificial intelligence
• Hardware control

Therefore, we spent time this week brushing up on Python. Following the same approach that we had used previously to move from Scratch to C, we looked at how we would move from programming in Scratch to Python.

Kevin then spent time explaining how to write a basic Python program to read an image from a webcam. Here is the code:

# We are using OpenCV
import cv2

# Capture webcam image
camera=cv2.VideoCapture(0)
val, img = camera.read()

# Display the image
cv2.imshow("Window display", img)

# Stop using the camera
camera.release
