Provided it doesn't take any arguments you can run the code with exec or
eval:
>>> def outer():
def inner():
print "inner called"
return inner()
>>> eval(outer.func_code.co_consts[1])
inner called
More usefully you could use the code object to construct another function,
e.g. if you wanted to change the values of some default arguments.
>>> types.FunctionType(outer.func_code.co_consts[1], globals())()
inner called
