Why do I have to repeat items in list slices in order to make this work?

I think indexing is best avoided when possible.

distros = {
    "debian": ("Ubuntu", "Mint", "Kali"),
    "Red Hat": ("Fedora", "CentOS", "Oracle"),
    "slackware": ("Mageia", "KateOS", "Slackintosh"),
}

for vendor in distros:
    for distro in distros[vendor]:
        print(f"{distro} is a {vendor} distro.")

Output:
Kali is a debian distro.
Fedora is a Red Hat distro.
CentOS is a Red Hat distro.
Oracle is a Red Hat distro.
Mageia is a slackware distro.
KateOS is a slackware distro.
Slackintosh is a slackware distro.
