How do I import everything in a subdir?

[Dfenestr8]

Hi.

I have a program which I want a plugin directory for. I figured the way to
go about that would be to just add a plugin/ dir to sys.path, and import
everything in it. Then my program can just execute the main() method of
each imported plugin.

Is that a good way to go about it?

If so, how do I import everything in the plugins dir? The method raises an
error as you can see.

>>> import sys
>>> import os
>>> sys.path.append("plugins")
>>> ls = os.popen("ls plugins").readlines()
>>> for x in ls:
...     plugs.append(x[0:x.rfind(".py")])
>>> for x in plugs:
...     import x
...
Traceback (most recent call last):
  File "<stdin>", line 2, in ?
ImportError: No module named x
