rename many pdf'S in a directory

[snippsat]

I have autocad batch print 50 files to adobe pdf. The problem is the default filename will add "Layout (1) .pdf" at the end of the filename.

How dos the raw filename look?
Let say as you say just add fooLayout (1).pdf hello worldLayout (2).pdf

import os
import re

for file_name in os.listdir('.'):
    if file_name.endswith('.pdf'):
        new_name = re.sub(r'L.*\)', '', file_name)
        # Always test print before doing chages to files
        print(file_name, new_name)
        #os.rename(file_name, new_name)

Output:
foo.pdf
hello world.pdf
