How do you fix a "TypeError: 'NoneType' object is not iterable" error in Python?

I’m working on a Python script, where I’m using a function to return a list of items from a database. However, when I try to iterate over the returned list, I get the error “TypeError: ‘NoneType’ object is not iterable.” I’ve checked the function, and it appears to be written correctly. I’m not sure if the problem is with the way I’m calling the function or something within the function itself. The function is supposed to return a list, but it seems like it’s returning a NoneType instead. This is causing my for-loop to crash and it’s really hindering my progress. How do I go about fixing this issue?

Please post your formatted code so people can try to help.
