I did what I should have done–I read the appropriate section of the picamera2 manual, Section 3.3. Starting and stopping previews.
“For example, the following script would start the camera system running, run for a short while, and then attempt to autodetect which preview window to use in order actually to start displaying the images:
I made the changes and this was the result:

When I ran ‘python take_photo.py’ I got this error: qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin “xcb” in “” even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.
