Hi,
What is the safest manner to extend search path for modules, minimizing
the likelihood of shooting oneself in the foot?
The system (which includes scripts and their shared modules) may be
checked out in several different locations, but a script in a
particular checked-out version of the system should only use modules
from that checkout location.
e.g. if the system contains a directory scripts/foo/ where all the
scripts are housed, and scripts/modules/ where all the modules are
housed, then is it correct for each script in scripts/foo/ to begin
with:
import sys, os.path
sys.path.append (os.path.join(s ys.path[0], "../modules"))
If so, is there a cleaner way of doing this than including the above
text in all scripts?
Thanks,
Joseph

Put that text in a module that is already on the path, and then import
that module.
Or mabye generalize it into a function:
import sys, os.path
def fixpath(*new):
sys.path.extend (os.path.join(s ys.path[0], x) for x in new)
This requires 2.4. Change it to ([os.path ... new]) for earlier versions.
Of course, I note that sys.path[0] is '', so the join doesn't do anything.

I'd like to modify the python search path depending on the source
directory of the script being started. The reason is: I use a version
control system, and the python scripts and modules are migrated
through several stages before they are used in production. A python
script running in a development environment should use different
modules - possibly in other directories then the script source
directory - than the same script running in a...

I have a Python program that I want to run in Jython so I can get Java

Apparently Jython does not use the PYTHONPATH environment variable. I

Hi,
I've been trying for days to make either boost.python or swig to
work for me. The one I have gotten the closest to is boost. Note that
this is for windows XP. I'm not much of an unix person besides doing
simple ls and copy paste.
What I have done is to download the boost library: C:\boost_1_34_0
I downloaded the bjam library: C:\boost-jam-3.1.14-1-ntx86

I'm new to python, running it under cygwin. This must be easy but I
haven't figured it out. I'm trying to run a script by typing:
python test.py
where test.py is in a directory I've added to PYTHONPATH, but test.py
is not found. Perhaps PYTHONPATH only applies to modules imported
within a script. I didn't notice an option to python to search the
standard path, like Perl -S.

I think I don't understand how the module search path works...
Let's say I have a folders called 'test'. Underneath it, I create two
more folders called 'foo' and 'bar'.
In 'foo', I create an empty '__init__.py' file, indicating that this
folder is a package 'foo'. I then create a simple python script
'foo.py' consisting of the following code:

I have a python script (part of a django application, if it makes any

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
