This line of code creates a compiled regular expression object named class_matcher using Python's re module. Let's break it down:

1. re.compile():

   • This function compiles a regular expression pattern into a regular expression object. It allows for more efficient matching of the pattern against strings.

2. "^Lyrics__Container":

   • This is the pattern being compiled. It means:
     • ^: Matches the start of a string.
     • Lyrics__Container: Matches the literal string "Lyrics__Container" at the beginning of a string.

What does the code do?

The class_matcher object can be used to check whether a string starts with "Lyrics__Container". For example, you could use it to match class names in HTML or CSS that begin with this prefix.
