Hi Adam, 

In the previous email, I forgot to mention that I have
already tried:

i = 0
while i < len(list1):
    print list1[i], len(list1[i])
    i += 1

However, I got:

soam! 5
1
Traceback (most recent call last):
  File "list1.py", line 11, in ?
    print list1[i], len(list1[i])
TypeError: len() of unsized object

Could I hear from you again?
Hoffmann
