Perhaps this will help you to see what's going on step by step.
Copy and paste each line one by one into your Python IDE, to see what it is doing.
Of course, the if ... else: has to be pasted in one go.
Then, when you understand what's happening, put lines 25 to 35 in a function and return newname.
I replaced the gaps in the new file names with underscore, because, if I had hundreds or thousands of photos to work on, I would do this in bash, and bash doesn't like the spaces!
Probably a good idea to standardize all the names to .jpg or whatever first.
