I have a python script, I want to add some changes in it, but as I've no idea about python would it be possible that I could add the changes myself?

I have a python script, the script basically fetch documents from another site. The script is running fine, but I have to change it a little bit, like I want the script to ignore the docs if they have only images. Secondly, I want the script to ignore the documents if they have already been fetched, either based on the created_at date from the documents table or the last date on which script got run. As I have mentioned in the question, would it be possible for me to these changes myself or not, as someone else has written the script? If anyone would like to help me, I'll surely share the code snippet. Thanks in advance :)
