So, on Unix, for a path separator, you type /. On Windows you can either do the same, or type \\. (Or (ab)use raw strings.) Okay, point taken, but I still think it's more a C(++) string thing than a Windows issue. I could of course argue that the backslash path separator is there for backward compatebility with Dos, but I won't, much to off topic...;-)) James Greetings from overcast Amsterdam, Jan -- http://mail.python.org/mailman/listinfo/python-list

However, you can say that using '\' as a path separator needs special treatment, because it is conventionally treated as an escape character.

Re: How can I import a py script by its absolute path name?
You probably actually want: import sys sys.path.instert(0, r'c:\xxx\yyy') m = __import__('zzz', globals(), locals(), []) del sys.path[0] Because if another module named zzz exists in your path. Appending will pick those versions up first. Then you delete the path you just added so that you don't have any problems importing other modules that may have the same names a python files in the path you just added. -Chris On Thu, Jul 14, 2005 at 02:52:31PM +0300, Edvard Majakari wrote: could ildg [EMAIL PROTECTED] writes: I want to import c:\xxx\yyy\zzz.py into my programme, What should I do?

Thank you~ import sys sys.path.append('c:\xxx\yyy') sys.path.append('c:\\xxx\\yyy') or sys.path.append('c:/xxx/yyy') While this will work, I think the OP may want something simpler: my_mod = __import__('c:\\xxx\\yyy\\mymodule.py') especially if this is following up on the relative path workaround (in which case the result will be buried in the relative path import function). The sys.path solution is the technique you should be using to establish a top-level directory for your package. Once you do that, you can use __init__.py and dotted imports to get to everything in your package by absolute paths (that is, relative to the top-level package, rather than to each sub-package). This is the preferred Python approach in the current design. However, the idea that it would be desireable to import packages by something like ../main_package/other_subpackage/module2.py has been suggested, and you can implement something like this using the __import__ built-in as suggested above. -- Terry Hancock ( hancock at anansispaceworks.com ) Anansi Spaceworks http://www.anansispaceworks.com -- http://mail.python.org/mailman/listinfo/python-list
