When importing a module, python first looks in the same directory as
the module doing the importing.  You really don't need to be futzing
with sys.path for that.

Eg:

$ pwd
/home/dman

$ ls /tmp/foo
mod1.py
mod2.py

$ cat /tmp/foo/mod1.py

import mod2

print "mod1 done"

print
import sys
print sys.path

$ cat /tmp/foo/mod2.py

print "mod2 done"


$ python -S /tmp/foo/mod1.py

mod2 done
mod1 done

['/tmp/foo', '/usr/lib/python2.1/', '/usr/lib/python2.1/plat-linux2',
'/usr/lib/python2.1/lib-tk', '/usr/lib/python2.1/lib-dynload']

$


As you can see, the directory the initial module was in (/tmp/foo) was
included as the first thing in sys.path.

Yes, Java is so bulletproofed that to a C programmer it feels like being in=
 a
straightjacket, but it's a really comfy and warm straightjacket, and the wo=
rld
would be a safer place if everyone was straightjacketed most of the time.
