lines = soup.select('div.ember-view > span.lt-line-clamp__line')
text = ''.join([line.find(text=True, recursive=False) for line in lines])
print(text)

您可以使用CSS选择器div#ember760来选择<div class="ember-view" id="ember760">和.get_text()方法：

from bs4 import BeautifulSoup


txt = '''
<div class="pv-recommendation-entity__highlights">
<blockquote class="pv-recommendation-entity__text relative">
<div class="ember-view" id="ember760"> <span class="lt-line-clamp__line">I know Abc from Data Analysis training sessions with abc,</span>
<span class="lt-line-clamp__line">Abc
is an enthusiastic candidature in training sessions. He is an</span>
<span class="lt-line-clamp__line">extremely capable and dedicated entry-level Data Science Analyst.</span>
<span class="lt-line-clamp__line">He is enhancing Analytics skills by his enthusiasm for learning new</span>
<span class="lt-line-clamp__line lt-line-clamp__line--last">
      things, and has learnt new tools like R, SPSS, and Pytho<span class="lt-line-clamp__ellipsis">...
            <a aria-expanded="false" class="lt-line-clamp__more" data-test-line-clamp-show-more-button="true" href="#" id="line-clamp-show-more-button" role="button">See more</a>
</span></span>
<!-- --><span class="lt-line-clamp__ellipsis lt-line-clamp__ellipsis--dummy">... <a class="lt-line-clamp__more" href="#" role="button">See more</a></span></div>
</blockquote>
</div>
</li>
</ul>
<!-- --></div>
</div></div>'''

soup = BeautifulSoup(txt, 'lxml')

print(soup.select_one('div#ember760').get_text(strip=True, separator='\n'))
