def show_magicians(magicians_list):

for magician in magicians_list:

magicians_list.append(magician)
list_of_dudes = ['houdini','david blaine','jebus']
make_great(list_of_dudes)
show_magicians(list_of_dudes)
print(list_of_dudes)
为什么第二个功能不起作用?我试图将花花公子列表中的每个魔术师更改为“ [[Magician] The Great”,但我不断遇到存储错误。有什么建议吗?
谢谢,

您不应该追加到列表中,而应将每个元素替换为其“出色”版本。
def make_great(magicians_list):
"""Make each magician great again."""
for i, magician in enumerate(magicians_list):
magician = magician + " " + "the Great"
magicians_list[i] = magician
您的版本将追加到要迭代的列表中。结果,它永远不会结束,因为它会继续遍历新元素,并使它们变得更大(
houdini the Great the Great
),然后遍历这些元素(houdini the Great the Great the Great
),依此类推,直到耗尽内存。
