PDF comparision

i am trying to compare two pdf files and i can only use pdfminer, but the text extraction is not working same for both the files as the formatting and alignment is different and it will be in the same way and no way to make the format same.
I have already messed up my python file and cant generate a proper comparision of pdf
i am mainly trying to do comparison section wise
please give me apython code or ideas on how i can do it or the prompts
