lyrics = """
You think you've got it, oh, you think you've got it
But “got it” just don't get it 'til there's nothing at all
We get together, oh, we get together
But separate's always better when there's feelings involved
If what they say is “Nothing is forever”
Then what makes, then what makes, then what makes
Then what makes, what makes, what makes love the exception?
So why oh, why oh, why oh, why oh, why oh
Are we so in denial when we know we're not happy here?
Y'all don't want to hear me, you just want to dance

Use lower() to convert your song to lowercase.

Part 2: Replacing characters that aren't part of words

Use replace to replace ! ( ) , . and other punctuation characters in your song with spaces.

Tip: you can replace each character one by one, or you can make a list of non-letter characters and use a loop to replace each character in turn

Part 3: How many lines, how many words?

Use split() to break your (lowercase, punctuation-free) song into words. How many words does your song have?

Use split() to break your song into lines. What escape character do you need to use? How many lines does your song have?

Part 4: Word Frequency

How many times does each word appear in your song?

Start with your list of words in your song.

Create a dictionary of words, and how many times they appear in the song.

How many unique words are in your song? Print the number of unique words.

Part 5: Table, alignment

Display your word frequency counts in a table. Use string formatting and alignment to space your data into a table with neatly aligned columns.

If you have words with upper and lowercase forms, or words with punctuation in, revisit part 1 and 3 and make sure you lowercase your lyrics and remove all punctuation
