python为何导入模块调用函数出错

Question

我在sublime和editplus里写python，如下几句：

-*- coding: utf-8 -*-

import shutil
shutil.copyfile('hello.txt', 'hello2.txt')
提示错误：
Traceback (most recent call last):
File "F:\Python\exercise\文件处理\shutil.py", line 2, in
import shutil
File "F:\Python\exercise\文件处理\shutil.py", line 3, in
shutil.copyfile('hello.txt', 'hello2.txt')
AttributeError: 'module' object has no attribute 'copyfile'
