Re: problem with import / namespace

Hi
I have a problem that the solution to it must be very simple but i
couldnt fint it's answer in the internet so far (i searched for couple
of days)
the problme is as follows:

i have two directories e.g. "\\1" and "\\2"
in each directory i have two files with the same names e.g. "tmp1.py"
and "tmp2.py"
So this is what you have:

/1/tmp1.py
/1/tmp2.py
/2/tmp1.py
/2/tmp2.py
each tmp2.py file imports tmp1 from its same directory (import tmp1) -
thats the problem
if i execute one file (\\1\tmp2.py) than the execution is ok
but when i try after that to execute the second file (\\2\tmp2.py)
than the tmp1 file from the wrong directory ( - directory 1 in this
case) is imported instead.
When you try to import a module, python starts to search for it. The was
it does the search is very well defined. It mostly depends on the
current directory and sys.path. You can read more about this here:

http://docs.python.org/tut/node8.html#searchPath

This is very basic thing - you should read and go through the tutorial
before asking questions like this. :-)
i tried many things to try to solve it, i removed the previous path
from sys.path and added the new one, i tried to change current working
directory with os.chdir()
I tried to delete from locals and from globals the name tmp1 before
running the second file but nothing worked.
please help
The problem is still not well defined. Python works as expected and
documented, but apparently you do not know how to import 1/tmp2.py from
2/tmp1.py. There are several ways to do it, and we cannot tell which
one is correct. It depends on what are these modules for.

Here are the solution that you would use (most likely) as a beginner:
#1 first, rename your "1" and "2" directories to "one" and "two". If you
are creating a package with modules, then you have to define the
package's name with its directory. Since identifiers cannot begin with
digits in Python, you need to use an identifier-like name for your
subdirs. It is a good idea anyway. A package name called "1" would tell
nothing about what it does?
#2 place your main application in /app/app.py
#3 create /app/one/__init__.py and /app/two/__init__.py files (they can
be empty)
- inside your app.py file either make sure that the current dir is /app,
or insert /app in the first place in sys.path
Then for example, inside two/tmp1.py you can do this:
import one.tmp1
import one.tmp2
import two.tmp1

one.tmp1.somefu nc()
two.tmp1.somefu nc()
You got the idea.

Hi, I have a scenario where I have a master schema that defines a number of complex and simple types. I then have a number of other schemas (with different namespaces) where I would like to reuse some of these master complex and simple types. This I believe will assist me in transforming between the master schema and the other smaller schemas that contain a subset of the elements in the master schema. I understand that I can import an...

Our webhost (www.usbusinessweb.net) had a W2K IIS5 server crash after a scheduled hard-boot occurred during a ms-security patch install overnight. They couldn't get the server working again so they transferred our site www.orbisoft.com to a new W2003 IIS6 server they set up. That was a week ago. Since that transfer, all of our ASPX pages that use Access2000 databases have stopped working.
