I have a list containing the numbers from 1-10.

list = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

I now want to remove all numbers smaller than 5.

for i in list:
    if i < 5:
        list.remove(i)

If i now print the list,

print list

I get this:

[2, 4, 5, 6, 7, 8, 9, 10]

which seems very odd to me. I may be missing something or just overlooking a simple mistake, but I don't see it.

Thanks for your help

You're modifying the list as you iterate over it, this is why you get this behaviour – EdChum Jun 05 '15 at 14:38

Don't remove items form a sequence you are currently iterating over. You will get unexpected results. – kylieCatt Jun 05 '15 at 14:39

If your list is ordered as in your example, you can just `print list[5:]` – Avión Jun 05 '15 at 14:40
print list[5:] wont give the desired output rather its giving [8, 9, 10] – Pralhad Narsinh Sonar Jun 05 '15 at 14:45

On what basis - question is marked as a duplicate? Its not duplicate at all. Lets try to think about the new questions before flagging it duplicate. – Pralhad Narsinh Sonar Jun 05 '15 at 14:56
