Why can not import the module in sys.path?

root@rebuild:~# python3.4
Python 3.4.0 (default, Nov 27 2014, 13:54:17)
[GCC 4.7.2] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.path
['', '/root', '/root/Python-3.4.0/Lib/site-packages/}', '/usr/local/python3.4/lib/python34.zip', '/usr/local/python3.4/lib/python3.4', '/usr/local/python3.4/lib/python3.4/plat-linux', '/usr/local/python3.4/lib/python3.4/lib-dynload', '/usr/local/python3.4/lib/python3.4/site-packages']   
>>> import os
>>> os.system("ls  /root/Python-3.4.0/Lib/site-packages/")                      
test.py  README
0
>>> import  test.py
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named 'test'

It is strange that why can't import test module which is in the sys.path "/root/Python-3.4.0/Lib/site-packages/"?

import test.py

You imported your module test with the extension .py. So the import will try to find module named py in package test. 

import test

Would be the correct syntax for importing a module.

For example :

>>> import string
>>> string
<module 'string' from 'C:\Python27\lib\string.pyc'>

Here string is module. But if you try to import string.py it treats string as package and trys to import py module.

>>> import string.py
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named py

And you should also fix your site-packages path in sys.path which has '}' symbol at the end which is invalid path.

For two reasons:

  • Your sys.path is messed up (there's a trailing }).
  • You're supposed to import test, not import test.py.

Please read the Python tutorial's section on modules: https://docs.python.org/3/tutorial/modules.html
