Change file names inside a directory using python

I need to change file names inside a folder

My file names are

BX-002-001.pdf
DX-001-002.pdf
GH-004-004.pdf
HJ-003-007.pdf

I need to add an additional zero after '-' at the end, like this

BX-002-0001.pdf
DX-001-0002.pdf
GH-004-0004.pdf
HJ-003-0007.pdf

I tried this

all_files = glob.glob("*.pdf")
for i in all_files:
    fname = os.path.splitext(os.path.basename(i))[0]
    fname = fname.replace("-00","-000")

My code is not working, can anyone help?

fname = fname.replace("-00","-000") only changes the variable fname in your program. It does not change the filename on your disk.

you can use os.rename() to actully apply the changes to your files:

all_files = glob.glob("*.pdf")
for i in all_files:
    fname = os.path.splitext(os.path.basename(i))[0]
    fname = fname.replace("-00","-000")
    os.rename(i, os.path.join(os.path.dirname(i), fname ))
