Understanding the Regular Expression: ^\s*$\n

This regular expression is used to identify and remove blank lines from text.

• ^: Matches the beginning of a line. Since we're using the `re.MULTILINE` flag in Python, each line in the text is treated as a separate unit.
• \s*: Matches zero or more whitespace characters (spaces, tabs, newlines).
• $: Matches the end of a line.
• \n: Matches a newline character.

In essence, this regular expression matches a line that:

1. Starts with the beginning of the line.
2. Contains zero or more whitespace characters.
3. Ends with the end of the line.
4. Is followed by a newline character.

Therefore, it effectively targets and matches blank lines that might contain spaces or tabs.
