True. The lambda expressions still exist on Python 3000 as there are no other "pythonic" alternatives to create anonymous functions. It was impossible at this time to come up with a better alternative to existing lambda expression that could support multi-line statements - much like Proc objects in Ruby for instance, without breaking existing Python rules (indentation rules for example). The existing lambda expression as such does not break any rules to be termed as unpythonic. Even 'map' and 'filter' exists on Python 3000 as most of the community believe them to be more simpler and readable than list comprehensions in many cases. Whether using them is pythonic or not - can be subjective ;-). But they are redundant variants of list comprehensions. The 'reduce' was removed in Python 3000 (or rather moved to functools, instead) to maintain consistency overall.
