>>> import htmltruncate
>>> str = "<p>You're not gonna lose the house, <b>everybody</b> has three mortgages nowadays.</p>"
>>> htmltruncate.truncate(str, 33)
"<p>You're not gonna lose the house, </p>"Options:
>>> htmltruncate.truncate(str, 33, full_word=True, ellipsis="...")
"<p>You're not gonna lose the house, <b>everybody</b></p>..."
