IndexError：列表分配索引超出范围 Python 3

Question

有人知道为什么我在这段代码中得到一个 IndexError 吗？

            global gegner
            global gegnerhp
            gegner = []
            gegberhp = []



            for i in range(1,anzahlgegner):
                random = randint(1,5)
                if random == 1:
                    gegner[i] = "goblin"
                    gegnerhp[i] = randint(10,50)
                elif random == 2:
                    gegner[i] = "ghost"
                    gegnerhp[i] = randint(10,50)
                elif random == 3:
                    gegner[i] = "hound"
                    gegnerhp[i] = randint(10,50)
                elif random == 4:
                    gegner[i] = "wolf"                        #LINE 147
                    gegnerhp[i] = randint(10,50)
                elif random == 5:
                    gegner[i] = "goblin"
                    gegnerhp[i] = randint(10, 50)
                print("* {0} with {1} HP".format(gegner[i]),gegnerhp[i])

例如，当随机数为 4 时，我收到以下错误：

  File "C:/Users/Fabio/PycharmProjects/test\dungeon.py", line 147, in run
gegner[i] = "wolf"
  IndexError: list assignment index out of range

也许我对列表/数组的声明是错误的？...

你的列表gegner和gegnerhp都是空的，因此访问它们会给你一个错误。
