当我从空闲状态导入“http.server”时,它会正常工作,但当我运行一个具有“importhttp.server”的python文件时,会出现一个错误

当我使用:

>>> import http.server

在 IDLE 没有任何错误。
但当我使用这段代码时:

import http.server
from http.server import BaseHTTPRequestHandler
from http.server import HTTPServer

def run(server_class = HTTPServer, handler_class = BaseHTTPRequestHandler):
    server_address = ('', 8000)
    httpd=server_class(server_address, handler_class)
    httpd.serve_forever()


run()

存在如下错误:

Traceback (most recent call last):
  File "<frozen importlib._bootstrap>", line 2195, in _find_and_load_unlocked
AttributeError: 'module' object has no attribute '__path__'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/home/toton/Projects/http.py", line 1, in <module>
    import http.server
  File "/home/toton/Projects/http.py", line 1, in <module>
    import http.server
ImportError: No module named 'http.server'; 'http' is not a package

请帮助!
