As an experiment, I did this:
letters=['a','b','c','d','e','f','g','h','i','j','k','l']
for i in letters:
letters.remove(i)
print letters
The last print shows that not all items were removed ? (every other was).

>>> ================================ RESTART ================================
>>>
['b', 'd', 'f', 'h', 'j', 'l']

What's the explanation for this ? How it could this be re-written to remove every item ?
