newbie question about import

[Craig]

hi all,

is there a python equivalent to the C preprocessor statement #include
relative-or-absolute-path?
i want to import code in a specific file into my script.

thanks,
craig

anwering my own query...i see that this a common question amongst python
newbies. i shall look around the web a bit and see if i can work it out.

ok, so i understand that there are important differences between import and
#include, but the thing i don't get is why you can't do something like
import "d:\dev\build\config.py"?

is it good style to do this to get the above behaviour:

import sys
sys.path.append(/my/include/path)
import my-include-file

... is it good style to do this to get the above behaviour:

import sys
sys.path.append(/my/include/path)
import my-include-file

Assuming you quote properly, and your file is nicely named:
sys.path.append('/my/include/path')
import my-include-file

Typically you will only have one or two directories you need
to add, and you _can_ make a file "my.pth" which consists
of the directory names you care about, and throw "my.pth"
in <pythontop>/lib/site-packages

The idea is to keep the source as portable as possible. Each OS
has a different syntax for directory names; you could easily
become non-portable that way. Note the "append to sys.path"
solution does not address this. Also note, code like:

import sys
if myextdir not in sys.path:
sys.path.append(myextdir)

may work a little better for you.
