If need to search more specific as mention before you call
text(and use tool on that text).Example this is a typical way with text and values are in separated tags.
from bs4 import BeautifulSoup html = '''\ <html> <head> <meta charset="UTF-8"> <title>Title of the document</title> </head> <body> <p id="calc_text">Calculation Results is</p> <span class="BMIScore">158</span> </body> </html> ''' soup = BeautifulSoup(html, 'lxml')Use it:
>> p = soup.find('p')
>>> p
<p id="calc_text">Calculation Results is</p>
>>> type(p)
<class 'bs4.element.Tag'>
>>> # Calling text take it out of BS to a string
>>> p = soup.find('p').text
>>> p
'Calculation Results is'
>>> type(p)
<class 'str'>The value is in separated tag.>>> bmi = soup.select_one('.BMIScore')
>>> bmi
<span class="BMIScore">158</span>
>>> bmi.text
'158'
# Or if integer is needed
>>> int(bmi.text)
158
