How to use "for" and "while" to capture cell tags from multiple tables in an html file?

I have several HTML files that I need to capture the data inside the tables, to launch in the database, but I can not navigate the html tree to find the tags that are cells, the html is this:

<div class="details">
   <div class="title-table"><h2> BEAUNE</h2>
   <div class="table-responsive">
      <div class="table-towers">
        <div id="table472dc5e9b46304cf95865f7db6c459aa" class="collapse in table-content">
           <div class="table-towers">
                 <div class="table-row">
                    <div class="table-cell build_type">Apartamento</div>
                    <div class="table-cell area_useful">220m²</div>
                    <div class="table-cell rooms">3</div>
                    <div class="table-cell garage">4</div>
                    <div class="table-cell bird_estimate_average">R$ 2.816.344,33*
            <p><small>(R$ 2.393.892,68 a R$ 3.238.795,98)</small></p>
        </div>
                 <div class="table-row">
        <div class="table-cell build_type">Cobertura</div>
                    <div class="table-cell area_useful">396m²</div>
                    <div class="table-cell rooms">3</div>
                    <div class="table-cell garage">5</div>
                    <div class="table-cell bird_estimate_average">R$ 5.069.419,80*
                             <p><small>(R$ 4.309.006,83 a R$ 5.829.832,77)</small></p>
                     </div>
   <div class="title-table"><h2>BERGERAC</h2>
      <div class="table-responsive">
          <div class="table-towers">
               <div id="table0b60c9a0a450b921186c91102da447d9" class="collapse table-content">
                   <div class="table-towers">
                       <div class="table-row">
                            <div class="table-cell build_type">Apartamento</div>
                    <div class="table-cell area_useful">220m²</div>
                    <div class="table-cell rooms">3</div>
                    <div class="table-cell garage">4</div>
                    <div class="table-cell bird_estimate_average">R$ 2.816.344,33*
                               <p><small>(R$ 2.393.892,68 a R$ 3.238.795,98)</small></p>
                 </div>
                                            <!-- asdasd -->
                </div>
                        </div>

I have 10 more tables, inside an HTML file, which follows the same structure, so I thought I'd do a "for" to get the title-table tag, which is the name of the table like this:

for id_torre in soup.find("div",{"class":"details"}).findAll("div",{"class":"title-table"}):#.findAll("h2"):
nm = id_torre.find("h2")
print(nm)

And with the list of table titles, I thought of the "while" so that it finds the table with each title and then it captures the data of the cells in each line, for later I launch in the database:

while len(id_torre) >0:
nm = id_torre
print(nm)

tipo = soup.find("div",{"class":id_torre}).find("div",{"class":"table-cell build_type"})
print(tipo)

m2_util = soup.find("div",{"class":id_torre}).find("div",{"class":"table-cell area_useful"})
print(m2_util)

dt = soup.find("div",{"class":id_torre}).find("div",{"class":"table-cell rooms"})
print(dt)

But it does "none" in all fields and loops endlessly. What's wrong with the code? I'm new to programming and python is the first language I'm learning.
