python中list和list[:]有什么区别?

What, if any, is the difference between list and list[:] in python?

推荐答案

阅读时，list是对原始列表的引用，而list[:]浅-复制列表.

When reading, list is a reference to the original list, and list[:] shallow-copies the list.

分配时，list(重新)绑定名称和 list[:] 切片分配，替换之前列表中的内容.

When assigning, list (re)binds the name and list[:] slice-assigns, replacing what was previously in the list.

另外，不要使用 list 作为名称，因为它会影响内置.

Also, don't use list as a name since it shadows the built-in.
