getattr is returning character '>' instead of mehtod
I have a class defined in feat.py
class feat:
def __init__(self):
print 'feat init '
pass
def do_something(self):
return true
Now I am calling the following:
from feat import *
f=feat()
for i in dir(f): #feature_functions:
i_str = str(i)
print 'f has this attribute', hasattr(f,i)
print 'f has attribute value', getattr(f,i)
I am getting output:
feat init
f has this attribute True
f has attribute value >
I tried using i_str like the following
print 'f has this attribute', hasattr(f,i_str)
print 'f has attribute value', getattr(f,i_str)
I am getting the same output.
Shouldn't the output look like the following?
f has this attribute True
f has attribute value <function do_something at 0x10b81db18>
Would appreciate any suggestion. I am using Python 2.7.

I made minor changes to your code to show more clearly what is going on:
from feat import *
f=feat()
for i in dir(f): #feature_functions:
print i, 'f has this attribute', hasattr(f,i)
print i, 'f has attribute value', getattr(f,i)
And this is the output I get:
feat init
__doc__ f has this attribute True
__doc__ f has attribute value None
__init__ f has this attribute True
__init__ f has attribute value <bound method feat.__init__ of <feat.feat instance at 0x0000000004140FC8>>
__module__ f has this attribute True
__module__ f has attribute value feat
do_something f has this attribute True
do_something f has attribute value <bound method feat.do_something of <feat.feat instance at 0x0000000004140FC8>>
Which is what we both expect. The chief difference is that the changed code isn't calling str(). I suspect you may have redefined str(), possibly in some earlier iteration of the code, and the redefinition is still lying around in your shell session's namespace. If so, starting a fresh interpreter session with only the code you present should solve the problem.
