Python supports LSP, does it?

[Andy Leszczynski]

wikipedia 
(http://en.wikipedia.org/wiki/Python_programming_language#Object-oriented_programming) 
says:
"""
Python's support for object oriented programming paradigm is vast. It 
supports polymorphism [...] fully in the Liskov substitution 
principle-sense for all objects.
"""

Just wondering if it is true statement. Is not LSP more a quality of the 
desing of class hierachy rather then language itslef? Comments?
