I'm new to camera input in Pygame and struggling to resize the image onto a surface. I keep looking things up and copying examples, and I'm not sure how to turn that into actual learning. Where should I start?
How do I resize a camera image onto a Pygame surface?

Break it into separate steps: get a camera frame as a Pygame Surface, scale that frame to the size you want, then blit the scaled surface onto your destination. Look at the Pygame camera documentation for capturing a frame and pygame.transform.scale for resizing it.
Check the size of the captured frame and the destination surface as you go. If the result looks stretched, choose dimensions that preserve the frame's aspect ratio instead of forcing it to fill the whole surface.

Looking things up is normal, especially when you're using a library feature for the first time. Try a small example, then change one thing at a time and see what happens. Once you can explain what each call does, you're doing more than copying.

Use the documentation alongside any example you find. Check what each function expects and returns, particularly whether it gives you a new surface or draws onto an existing one. You don't need to memorize the API, but knowing where to check it makes the next problem easier.

It also helps to test the captured frame without scaling first. That tells you whether the trouble is with capture or with the resize and blit steps.
