Is there a way to use methods dynamically within a for loop in python?

Question

Is there a way to use methods within a loop in Python? Something like the following:

obj=SomePythonObject()
list_of_methods=dir(obj)
for i in list_of_methods:
    try:
        print obj.i()     
    except:
        print i,'failed'

This seems potentially dangerous... Better hope that SomePythonObject doesn't have a deleteUsersHardDrive method. — Kevin

I understand - just trying out a new Python API that doesn't have good documentation and got bored with trying out all the methods manually. Thanks for pointing it out though — CiaranWelsh

Yes that's possible, use callable and getattr:

obj=SomePythonObject()
list_of_methods=dir(obj)
for i in list_of_methods:
    try:
        item = getattr(obj, i, None)
        if callable(item):
            item()     
    except:
        print i,'failed'
