To understand why your code doesn't work, run this:

items = ['a', '', 'b', '', 'c', '', 'd', '', 'e', '']

print(len(items))

for index, item in enumerate(items):
&nbsp;&nbsp;&nbsp; print(index, repr(item), items)
&nbsp;&nbsp;&nbsp; if item == '':
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; items.remove('')

When you remove an item, all the remaining items slide over one position, into 
the slot that has already been inspected. That means that they get skipped.
