How to declare a dictionary with inline function

Do I have to formally define a function before I can use it as an element of a dictionary?

def my_func():
  print 'my_func'

d = {
  'function': my_func
}

I would rather define the function inline. I just tried to type out what I want to do, but the whitespace policies of python syntax make it very hard to define an inline func within a dict. Is there any way to do this?

Answer

The answer seems to be that there is no way to declare a function inline a dictionary definition in python. Thanks to everyone who took the time to contribute.
