getattr() question

[Sledge]

Hi.

I am trying to dynamically load a class and attributes at run time.  I
do not know what classes will be referenced until run time.  I have it
loading the module correctly, but when I use getattr to access the
class and its attributes everything works except that I get additional
unwanted output.  The code



testclass.py:

#!/usr/bin/python

class testclass(object):

        myname = ""

        def __init__(self, name):
                self.myname = name

        def view(self):
                print "hello %s" % self.myname



test.py:

#!/usr/bin/python

import sys
sys.path.append('.')
from pprint import pprint

if __name__ == '__main__':
        myname = "testclass"
        myaction = "view"
        try:
                tc = __import__(myname)
                myclass = getattr(tc,myname)
                myinstance = getattr(myclass('python n00b'), myaction,
myaction)
                pprint(myinstance())
        except ImportError:
                "error"



Here is the output that I get:

user at debian:~/$ python test.py
hello python n00b
None
user at debian:~/$


Why is it printing 'None'?  What am I doing wrong.  I appreciate any
help.
