getattr is returning character '>' instead of mehtod












-1















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.
