You cannot delete elements from a list while you iterate over it, because the list iterator doesn't adjust as you delete items. SeeLoop "Forgets" to Remove Some Itemswhat happens when you try. An alternative would be to build a new list object to replace the old, using alist comprehensio...

If you really want to keep thefor-loopsyntax, then you need to iterate over a copy of the list (A copy is simply created by usinga[:]). Now you can remove items from the original list if the condition is true. foritemina[:]:ifeven(item):a.remove(item)# --> a = [1, 3] ...
These two options are likely to be the best solutions in most situations. However, there are other techniques to remove duplicates from a list. Using a loop to populate a new list A straightforward option is to iterate through the original list and add new items to a new list: ...
