What is in a class name?

# Sometimes we will ask you what the class type of an object is.

#

# For example, contemplate the text string "naval". What is it's class type?

# The koans runner will include this feedback for this koan:

#

# AssertionError: '-=> FILL ME IN! <=-' != <type 'str'>

#

# So "naval".__class__ is equal to <type 'str'>? No not quite. This

# is just what it displays. The answer is simply str.

#

# See for yourself:

self.assertEqual(__, "naval".__class__) # It's str, not <type 'str'>
