我有两个问题。
首先，如何找出Mac OS-X 10.6.8 Snow Leopard随附的Python模块（及其版本）？
其次，对雪豹和Tix怎么处理？我绝对不明白这一点。如果导入Tix，则没有错误。如果我以互动方式输入
>>> help(Tix)
我获得了有关使用Tix的信息。如果我再进一步的话，这会发生...
>>> root = Tix.Tk()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-tk/Tix.py", line 210, in __init__
_tkinter.TclError: can't find package Tix
>>>
哦，寡妇将打开，但我仍然会收到错误消息。我单击窗口，然后注意到菜单栏上显示“ Python”。在“文件”下，我看到“运行小部件演示”。我启动它，然后运行每个Tix演示。当我单击演示的“查看代码”时，我看到它全部在Tcl中（我假设是）。
Tcl / Tk是8.5x版，已经安装了Tix，可以用Python导入它，但不能使用？
最佳答案
Mac OS X 10.6随附Python 2.6.1。
该平台上的TKinter版本为Apple 8.5.7，存在已知问题；例如，IDLE将不运行它。
有关更多详细信息，请参见Python.org上的IDLE and tkinter with Tcl/Tk on Mac OS X page。
在10.6机器上help('modules')的终端输出：
$ sw_vers -productVersion
10.6.8
$ /usr/bin/python
Python 2.6.1 (r261:67515, Jun 24 2010, 21:47:49)
[GCC 4.2.1 (Apple Inc. build 5646)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> help('modules')
Please wait a moment while I gather a list of all available modules...

pygame和vboxapi（VBoxPython2_5，VBoxPython2_6，vboxapi，vboxshell）软件包是稍后在该计算机上安装的非默认加载项，其余应为标准问题。
