dict.clear() — Python Technical Interview Questions & Answers

dict.clear()

dict.clear()

  • dict.clear() works on a dictionary — labelled data like marks["Asha"] = 90. Keys map to values. Loop with .items() when you need both.
  • dict.clear() — output: {}.
  • Trap for dict.clear(): writing d[missing] in a viva. Prefer get when the key might not exist.
  { "Asha": 90, "Ravi": 85 }
         │           │
