The Solution

To accomplish this task, we will be using the BeautifulSoup library. In the Python code below, we will demonstrate how to extract the desired text from the aria-label attribute of the anchor tag.

Step-by-Step Implementation

Import BeautifulSoup: Start by importing the BeautifulSoup library.

Load the HTML content: Create a BeautifulSoup object with your HTML content. Here we will use the example you provided.

Locate the span tag: Use BeautifulSoup's find method to locate the span tag that contains the a tag.

Extract the aria-label value: Finally, use the get method to access the aria-label attribute.

Here's how the code looks:

Explanation of the Code

Parsing HTML: In the above code, we initialized a BeautifulSoup object by passing the HTML content and specifying the parser (in this case, 'html5lib' is used for better compatibility with HTML5 documents).

Finding the Element: The find method is used to locate the span tag that matches the specified class name. This is a crucial step to isolate our target element.

Accessing the Attribute: By referencing span.a['aria-label'], we directly access the aria-label attribute of the anchor tag. This gives us the string "좋아요 17".

Output: The final line of the code prints the output, which should display:
