Use slugify?

[andriyor]

With slugify

def get_url(artist: str, title: str) -> str:
    artist = slugify(artist.replace(".", "").replace("$", "s"), separator="_")
    title = slugify(title.replace("&", "and"), separator="_")
    if artist.startswith("the"):
        artist = artist[4:]
    amalgama_url = f"https://www.amalgama-lab.com/songs/{artist[0].lower()}/{artist}/{title}.html"
    return amalgama_url

Without sligify

def build_url(s: str) -> str:
    s = s.lower()
    chars_to_underscore = [" ", "-", "/", "'", "__"]
    for char in chars_to_underscore:
        s = s.replace(char, "_")

    s = s.replace("$", "s")
    s = s.replace("&", "and")
    s = s.replace("é", 'e')
    s = s.replace(".", "")
    return s


def get_url(artist: str, title: str) -> str:
    artist, title = map(build_url, [artist, title])
    if artist.startswith("the"):
        artist = artist[4:]
    amalgama_url = f"https://www.amalgama-lab.com/songs/{artist[0]}/{artist}/{title}.html"
    return amalgama_url
