How to replace just a file name in a file path with pattern

def listFiles(dir):
    rootdir = dir
        for root, subFolders, files in os.walk(rootdir):
            for file in files:
                yield os.path.join(root,file)
        return

    for f in listFiles(target):
        if pattern in f:
             os.rename(f,f.replace(pattern,'REPLACED'))

I have a file such as:

 "C:\Dir3.30\file_3.30.xml"

If I do

os.rename(f,f.replace(pattern,'REPLACED'))

both the occurances would be replaced. How can I make sure that just the file name is being replaced

I want:

"C:\Dir3.30\file_REPLACED.xml"

Split the filename off with os.path.split(), call str.replace() on just the name, and re-join:

path, name = os.path.split(f)
os.rename(f, os.path.join(path, name.replace(pattern, 'REPLACED')))
