Solve this:
{"quiz": "A very special island is inhabited only by knights and knaves. Knights always tell the truth, and knaves always lie. You meet 8 inhabitants: Ethan, Benjamin, Isabella, Zoey, Joseph, Henry, Luke, and Lily. In Ethan's words: "Benjamin is a knight or Zoey is a knight". Benjamin commented, "Ethan is a knight and Henry is a knight". "Benjamin is a knight if and only if Lily is a knave," Isabella claimed. "If Lily is a knave then Luke is a knight," Zoey claimed. According to Joseph, "Lily is a knight if and only if Luke is a knight". "Luke is a knave if and only if Isabella is a knave" - Henry. "Luke is a knight if and only if Zoey is a knave," Luke declared. According to Lily, "Luke is a knight". So who is a knight and who is a knave?", "names": ["Ethan", "Benjamin", "Isabella", "Zoey", "Joseph", "Henry", "Luke", "Lily"]

I'll solve this knights and knaves logic puzzle using the python-constraint library.

Perfect! I've solved the puzzle using python-constraint.
Solution
Knights (truth-tellers): Joseph, Henry
Knaves (liars): Ethan, Benjamin, Isabella, Zoey, Luke, Lily
Let me verify this solution quickly:
- Ethan (Knave) says "Benjamin is a knight or Zoey is a knight" → Both are knaves, so statement is FALSE ✓ (knave lies)
- Benjamin (Knave) says "Ethan is a knight and Henry is a knight" → Ethan is knave, so FALSE ✓ (knave lies)
- Isabella (Knave) says "Benjamin is a knight iff Lily is a knave" → Benjamin is knave, Lily is knave, so FALSE ✓
- Zoey (Knave) says "If Lily is a knave then Luke is a knight" → Lily is knave but Luke isn't knight, so FALSE ✓
- Joseph (Knight) says "Lily is a knight iff Luke is a knight" → Both are knaves, so TRUE ✓ (knight tells truth)
- Henry (Knight) says "Luke is a knave iff Isabella is a knave" → Both are knaves, so TRUE ✓ (knight tells truth)
- Luke (Knave) says "Luke is a knight iff Zoey is a knave" → Luke is knave, Zoey is knave, so FALSE ✓
- Lily (Knave) says "Luke is a knight" → Luke is knave, so FALSE ✓
The solution is consistent! Only Joseph and Henry are knights, and everyone else is a knave.
