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

dict.pop()

dict.pop()

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

Technical Interview Tip: get vs [] — one sentence + tiny dict of marks.
