The getFeature() returns a feature iterator, (here what's a python iterator) so you can use the next() function to get each item at a time.

Thank you @Joel and MrXsquared!! Joel are you talking about where to find info about commands like next()?

| Jan 10, 2023 at 18:19 | comment | added | Joel | Thank you! It works, and with @Mayo's suggestion even more elegantly so! My first thought was also to use .getFeatures(), but I didn't know how to index that. I couldn't find it in the PyQGIS documentation. Where should I look for documentation on these commands? | |

Or just first_id = next(source.getFeatures()).id().
