How can i extract the words which are starting with "icon" from HTML code using python

For your specific case you can get it as below, however i recommend using beautiful soup for working with wide problems, remember, Special cases aren't special enough to break the rules.

text = """
<a class="tel ttel">
<span class="mobilesv icon-hg"></span>
<span class="mobilesv icon-rq"></span>
<span class="mobilesv icon-ba"></span>
<span class="mobilesv icon-rq"></span>
<span class="mobilesv icon-ba"></span>
<span class="mobilesv icon-ikj"></span>
<span class="mobilesv icon-dc"></span>
<span class="mobilesv icon-acb"></span>
<span class="mobilesv icon-lk"></span>
<span class="mobilesv icon-ba"></span>
<span class="mobilesv icon-nm"></span>
<span class="mobilesv icon-ba"></span>
<span class="mobilesv icon-yz"></span>
</a>
"""

result = [word.split('"')[0] for word in text.split() if word.startswith('icon')]

print(result)

output:

['icon-hg', 'icon-rq', 'icon-ba', 'icon-rq', 'icon-ba', 'icon-ikj', 'icon-dc', 'icon-acb', 'icon-lk', 'icon-ba', 'icon-nm', 'icon-ba', 'icon-yz']
