You can use glob to find all the html files:

from glob import glob
import os
pre = "xyz_"
[os.rename(f, "{}{}".format(pre, f)) for f in glob("*.html")]

html files starting with a . should be ignored as glob treats filenames beginning with a dot (.) as special cases..

def glob(pathname):
    """Return a list of paths matching a pathname pattern.

    The pattern may contain simple shell-style wildcards a la
    fnmatch. However, unlike fnmatch, filenames starting with a
    dot are special cases that are not matched by '*' and '?'
    patterns.

    """
    return list(iglob(pathname))

Try -

import os
[os.rename(f, 'xyz_' + str(f)) for f in os.listdir('.') 
if ((not f.startswith('.')) and f.endswith(".html"))]
