Ah. :))
Why does the "print" statement return a syntax error here?

>>> lambda: print("hallo")
  File "<stdin>", line 1
    lambda: print("hallo")
                ^
SyntaxError: invalid syntax

Unfortunately I want to assign a handler function to an object and something
like this does not work:

>>> class Foobar(object): pass
...
>>> a = Foobar()
>>> def a.handler():
  File "<stdin>", line 1
    def a.handler():
         ^
SyntaxError: invalid syntax

But wrapping print into a myprint function works :)


Thanks,
