The problem is slightly weird, just because you need to clarify what it
means to take the length of a non-list. From the examples above, it
sounds like we'd like to define the "length" of a non-list to be one. Is
that right?
Can you write a function called length() that takes a thing and returns
the "length" of that thing?
######
def length(something):
... ## fill me in
######
For example, we'd like to see:
length("spam!") ==> 1
length(2) ==> 1
length(['Ted', 'Rock']) ==> 2
If you can define this you should be able to use this to solve your
problem.
When you're defining length(), you may find the built-in function "type()"
useful. For example:
######
>>> type(5)
<type 'int'>
>>> type([1, 2, 3])
<type 'list'>
######
Good luck!
