[Tutor] Problems with changing directory.

[Kent Johnson]

Until you get this working it might be better to omit the try block 
completely. Then an exception will give you a stack trace and a precise 
error message. If you don't understand the error message, post it here and 
we will help. Once you have it working you can add in try blocks that catch 
specific, expected errors and handle them in a user-friendly way.

Also, you can test specifically to see if a path exists using os.path.exists().
