定義后如何解決“名稱未定義”？

Question

我收到一個錯誤“ NameError：名稱'first_name'未定義”。

narek = {
    "first_name": "Narek",
    "last_name": "Kuloyan",
    "age": 27,
    "city": "Yerevan",
    }
…
people = [narek, tigran, karen]
for mard in people:
    for tvyal, info in mard.items():
        anun = info[first_name] + info[last_name]
        print("Anun azganun: "+ anun.title())
        print("\nTariq: " + str(info[age]))

Answer 1

如果我正確理解了您期望實現的目標，那么此代碼就可以完成工作。

narek = {
    "first_name": "Narek",
    "last_name": "Kuloyan",
    "age": 27,
    "city": "Yerevan",
    }

people = [narek]

for mard in people:
    anun = mard['first_name'] + mard['last_name']
    print("Anun azganun: "+ anun.title())
    print("\nTariq: " + str(mard['age']))
