You can install OpenCV in Python using the Anaconda prompt (Anaconda 3) by following the given two steps only. I highly recommend you get the “Computer Vision: Models, Learning, and Inference Book” to learn Computer Vision.
Step 1 (Anaconda)
Open the Anaconda Prompt (anaconda 3) from the search bar. If Anaconda Prompt is not installed then first install it by using this method.
Step 2 (OpenCV)
pip install opencv-python
