Hi everybody, it is my first post in this newsgroup.
I am a newbie for python though I have several years development experience in
c++.
recently, I was stumped when I tried to del item of a list when iteration.
here is the wrong way I did:
lst = [1, 2, 3]
for i in lst:
print i
if i == 2:
lst.remove(i)
the result is:
1
2
>>>
as you would see, '3' is missing. this problem is caused by 'lst.remove(i)'.
apparently, 'marked-and-sweep' is a solution to deal with this issue.
but I think there SHOULD BE more 'wise' trick. I want to get your help.
Thanks in advance.
