Even when you do get what lambda means and how use it,

because the function object resulting from lambda does not have a proper

An alternative is
[name for name, value in dic.itervalues() if value == age]
In Python 3, remove 'iter'. It this is not homework and you are not
otherwise forced to start with Python 3, I (and some others here)
recommend starting with Python 3.
