Added code tag in your post,look at BBCode on how to use.

on line-32 add this:

os.chdir(filePath)

The reason for this is that os.listdir() return relative path,
then if not run code in same folders as pdf's will get FileNotFoundError.

FYI: There are packages available that may do what you need. see: https://pypi.org/project/merge-pdf/
