import glob
glob.glob("*.html") # returns a list of all filenames you are looking
for
---------
import re
m = re.search(regular_expression_testing_for_string_of_code,
string_with_contents_of_page) # checks if your snippet is there
if m is None:
new_contents = re.sub(r"(?xis) <body .*?>", lambda m: m.group() +
your_snippet_of_code, string_with_contents_of_page) # Add the snippet
to the body. I use a function as the replacement in case your snippet
has backreferences in it for some reason. If it doesn't, feel free to
use r"\0" + snippet_of_code.
