python - Importing a module dynamically using imp

Question

I am trying to import a module from a different directory dynamically. I am following an answer from this question. I have a module named bar in a directory named foo. The main script will be running in the parent directory to foo.

Here is the code i have thus far in my test script (which is running in the parent directory to foo)

#test.py
import imp

mod = imp.load_source("bar","./foo")

and code for bar.py

#bar.py
class bar:

    def __init__(self):
          print "HELLO WORLD"

But when i run test.py I get this error:

Traceback (most recent call last):
  File "C:Documents and SettingsuserDesktopRBRest.py", line 3, in <module>
    mod = imp.load_source("bar","./foo")
IOError: [Errno 13] Permission denied

Answer 1

imp.load_source requires the pathname + file name of the module to import, you should change your source for the one below:

mod = imp.load_source("bar","./foo/bar.py")
