Sample Questions:
How can you extract the value of a specific HTML attribute from a BeautifulSoup object?
a) By using the .get('attribute_name') method.
b) By using the .attribute_name syntax.
c) By using the .attribute('attribute_name') method.
Explanations:
The correct answer is a) By using the .get('attribute_name') method.
To extract the value of a specific HTML attribute from a BeautifulSoup object, you can use the .get('attribute_name') method on a Tag object. This method allows you to retrieve the value of the specified attribute by providing its name as an argument.
