How do i set the PYTHONPATH variable
?
From answers to my query on "editing path" I
realized that this is what should be done if i want to include another folder in
the Python search path.
I tried:

sys.path.append('additional path')
but it worked only at runtime and is forgotte

"is" is object identity comparison while
"==" is object value comparison

they give different results when you have two different objects

I've been using python is 1.5* but haven't used `is` that much.
1)where do `is` and `==` yield the same results?
2)where do they not yield the same results?
3)is there a special method for `is'.
4)Pointers to docs are welcome.

Hello,

Hi Eli,
You really dont have to edit the search path, because if all the files lie in the same-directory as the top-level file, then Python automatically includes that directory in its search path.
