Python Path Dictionary

Hi,

Do the Python Paths come in the form of a dictionary where I can
access a particular path my its key in the registry?

For example, in PythonWin Tools>>Edit Python Paths shows the name as
well of the address of each path

Thanks,

Aine

If by "Python Paths" you mean the list of directories searched when
doing an import, then it is a list (not a dictionary and you can access
it as sys.path.

Here it is on both my Linux and Windows systems:
>>import sys
sys.path
['', '/usr/lib/portage/pym', '/usr/lib/python25.zip',
'/usr/lib/python2.5', '/usr/lib/python2.5/plat-linux2',
'/usr/lib/python2.5/lib-tk', '/usr/lib/python2.5/lib-dynload',
'/usr/lib/python2.5/site-packages',
'/usr/lib/python2.5/site-packages/Numeric',
'/usr/lib/python2.5/site-packages/PIL',
'/usr/lib/python2.5/site-packages/gtk-2.0']
>>import sys
sys.path
['', 'C:\\WINDOWS\\system32\\python24.zip', 'C:\\cygwin\\home\\Gary',
'c:\\python24\\DLLs', 'c:\\python24\\lib',
'c:\\python24\\lib\\plat-win', 'c:\\python24\\lib\\lib-tk',
'c:\\python24', 'c:\\python24\\lib\\site-packages',

Yeah, that's exactly what I'm talking about, but I don't want the
list, I want to access a certain path by name. I'm guessing I'm going
to have to write a function to do this that reads the value from the
registry.

The elements of the path don't have names - they are a list of
directories. You are mistaking Pythonwins configuration options (like
where it searches for modules) for the python path.

Note that the registry entry "PythonPath" (which is not respected by
Python, but used by Pythonwin to override the default python path) is
a semi-colon separated list, not a series of keys.

Your right with regard to Python Win! Although, it can be both a semi-
colon seperated list and/or a set of keys. On my PC I have a default
key under python paths (with a list of paths), plus a set of keys with
their own individul paths. I can therefore install my python code in
any directory and manipulate these keys to find the modules I need.
