python3导入未查找模块

我正试图从一本书中测试一个例子,我得到一个ImportError

示例从:

开始
from tkinter import *
from PP4E.Gui.Tools.widgets import frame, button, entry

如果我在代码的开头加上import sys; print(sys.path),则输出为

['/Users/aaa/Documents/workspace/programming-python/PP4E/Lang/Calculator', 
 '/usr/local/lib/python3.4/site-packages/setuptools-12.2-py3.4.egg',
 '/usr/local/lib/python3.4/site-packages/pip-6.0.8-py3.4.egg',
 '/User/aaa/Documents/workspace/programming-python',... ]

这是我的programming-python目录的截断版本:

❯ tree
.
├── PP4E
│   ├── __init__.py
│   ├── Gui
│   │   ├── Tools
│   │   │   ├── __init__.py
│   │   │   └── widgets.py
│   │   └── __init__.py
│   ├── Lang
│   │   └── Calculator
│   │       ├── __init__.py
│   │       └── calc0.py
└── site-packages
    └── PP4E.pth

我收到的错误消息是:

❯ python3 calc0.py                                                            

Traceback (most recent call last):
  File "calc0.py", line 2, in <module>
    from PP4E.Gui.Tools.widgets import frame, button, entry
ImportError: No module named 'PP4E'

有人知道我要做什么才能让Python找到PP4E模块吗?感谢。

I had my [root@death public_html]# ls -la test.* -r-xr-xr-x. 1 infinitywhack www 342 May 12 23:36 test.php -rwxrwxrwx. 1 infinitywhack www 5 May 12 23:06 test.txt wrong -- the root directory is PYTHONPATH, not /Users. Thanks.
