cap - capture variable for webcam
ret - True or False to tell me if the webcam is working or not
cap.read() - reads the frame of the webcam
imshow - Shows the window of the cap (capture variable)
waitKey(1) - waits for key pressed every 1ms 
cap.release() - frees the webcam so other apps can use it
cv2.flip() - basically it just flips the webcam horizontally if 1 is the flip_value
