Python 3 类型错误 : can only concatenate tuple (not "str") to tuple

Question

我希望为村民分配 4 个选项中的随机名称以及 4 个选项中的随机响应，但当我不断收到“TypeError: can only concatenate tuple (not “str”) to tuple”时想要打印最终的名称和响应

def villager():
  responses = ("Hi", "Are you a hero?", "Are you from this village?", "There has been a dark shadow cast across the village")
  npcnamechoice = ("Talion", "Ratbag", "Mildreth", "Susan")
  random.choice(npcnamechoice)
  npcname = npcnamechoice + ": "
  print(npcname + "Hello my name is " + npcname + "would you like to talk")
  random.choice(responses)
  print("Press y to talk to the villager")
  if input() == "y":
    print(npcname + responses)
  else:
    print(npcname + "Goodbye")

Answer 1

您实际上并未捕获随机值。这本身只是调用函数，它没有重新分配npcnamechoice

random.choice(npcnamechoice)

因此，创建另一个变量，或内联它

 npcname = random.choice(npcnamechoice) + ": "

对响应执行相同的操作
