but I want it in a dictionary with this format:

Code:

maryhadalittlelamb.html: http://www.red.com, https://www.redyellow.com, http://www.zigzag.com
time.html: https://www.est.com, http://www.pst.com, https://www.cst.com

As you can see, there will be several urls inside of an html doc so there will be keys that can contain many values(urls).

...

Is each value of the dictionary:
(a) a list (or array) of URLs? or
(b) a comma-delimited string of URLs?

If you want (a), then try something like the following:

Code:

tut_links = {}
for subdir, dirs, files in os.walk('./html/tutorials/blah'):
    for tut in files:
        if tut.endswith(".html"):
            tut_links[tut] = []
            fpath = os.path.join("./html/tutorials/blah", tut)
            content = open(fpath, "r").read()
            file = BeautifulSoup(content, 'lxml')
            for links in file.find_all('a'):
                urls = links.get('href')
                tut_links[tut].append(urls)

Disclaimer: Completely untested; I don't have the module at the moment.

urlwatch

URLWATCH(1)							   User Commands						       URLWATCH(1)

NAME

       urlwatch - Watch web pages and arbitrary URLs for changes

SYNOPSIS

       urlwatch [options]

DESCRIPTION

       urlwatch  watches  a list of URLs for changes and prints out unified diffs of the changes. You can filter always-changing parts of websites
       by providing a "hooks.py" script.

OPTIONS

       --version
	      show program's version number and exit

       -h, --help
	      show the help message and exit

       -v, --verbose
	      Show debug/log output

       --urls=FILE
	      Read URLs from the specified file

       --hooks=FILE
	      Use specified file as hooks.py module

       -e, --display-errors
	      Include HTTP errors (404, etc..) in the output

ADVANCED FEATURES

       urlwatch includes some advanced features that you have to activate by creating a hooks.py file that specifies for which URLs to use a  spe-
       cific feature. You can also use the hooks.py file to filter trivially-varying elements of a web page.

   ICALENDAR FILE PARSING
       This  module allows you to parse .ics files that are in iCalendar format and provide a very simplified text-based format for the diffs. Use
       it like this in your hooks.py file:

	 from urlwatch import ical2txt

	 def filter(url, data):
	     if url.endswith('.ics'):
		 return ical2txt.ical2text(data).encode('utf-8') + data
	     # ...you can add more hooks here...

   HTML TO TEXT CONVERSION
       There are three methods of converting HTML to text in the current version of urlwatch: "lynx" (default), "html2text" and "re".  The  former
       two  use  command-line  utilities of the same name to convert HTML to text, and the last one uses a simple regex-based tag stripping method
       (needs no extra tools).	Here is an example of using it in your hooks.py file:

	 from urlwatch import html2txt

	 def filter(url, data):
	     if url.endswith('.html') or url.endswith('.htm'):
		 return html2txt.html2text(data, method='lynx')
	     # ...you can add more hooks here...

FILES

       ~/.urlwatch/urls.txt
	      A list of HTTP/FTP URLs to watch (one URL per line)

       ~/.urlwatch/lib/hooks.py
	      A Python module that can be used to filter contents

       ~/.urlwatch/cache/
	      The state of web pages is saved in this folder
