Question

In the interest of reusing some existing code that was defined as an instance method of a different class, I was tying to do something like the following:

class Foo(object):
  def __init__(self):
    self.name = "Foo"

  def hello(self):
    print "Hello, I am " + self.name + "."

class Bar(object):
  def __init__(self):
    self.name = "Bar"


bar = Bar()
Foo.hello(bar)

but that results in:

TypeError: unbound method hello() must be called with Foo instance as first argument (got Bar instance instead)

Is something like this possible?

I should have been clear that I know this is a bad idea. Obviously the real solution is a bit of refactoring. I just figured there must be a way, and it turns out there is.

Thanks for the comments.

Answer 1

Looks like this works:

Foo.hello.im_func(bar)

Hello, I am Bar.

I guess I need to read a this little harder…
