Find All!

We can also use the function .find_all() to find not only one but multiple tags using a list. For instance:

print(soup.find_all(["title","h1"]))


              1
            
print(soup.find_all(["title","h1"]))

The code above returns the list of all title and h1 tags in our HTML file.

We can also use functions as an argument to find:

def find_all_condition(tag):

    return tag.string == "City: New York"

print(soup.find_all(find_all_condition))


              123
            
def find_all_condition(tag):
&nbsp;&nbsp;&nbsp;&nbsp;return tag.string == "City: New York"
print(soup.find_all(find_all_condition))

The code returns all tags which contain only the text "City: New York".

If you feel uncomfortable with functions in Python, repeat them with the course.

The BeautifulSoup library can optimize work and save a lot of time extracting the data from web pages. However, sometimes even such a magic tool can't detect the needed information. In such cases, parse the needed information with the function .find() and regular expressions!
