Find class of an instance?

[Neal Becker]

Sounds simple, but how, given an instance, do I find the class?

inst.__class__

For example:

Python 2.5.2 (r252:60911, Aug  5 2008, 03:26:50)
[GCC 4.3.1] on linux2
Type help, copyright, credits or license for more information.
 x = hello
 x.__class__
type 'str'

I always do that with .__class__, not sure whether it is the best way:

 class A:
...  pass
...
 a = A()
 a.__class__
class __main__.A at 0xb7f01fbc
 a.__class__ == A
True

  inst.__class__

 Works for new-style classes only. The generic way to go is to use
 type(obj).

 op
 Note that in both cases, what you'll get back is the class object, not
 the class name
 /op

My I should shut up and check my facts :( Please everybody ignore
this brain fart.

It does not only sound simple. When 'inst' is your instance, then

  inst.__class__

or

  type(inst) 

is the class.

Best,
