i wanted to remove all elements form list individually using list.remove(element) so, i made code:
a=[12,34,23]
for i in a:
a.remove(i)
print(a)
But I got:
[34]
Why did this happen?

Because you shouldn't modify the list while iterating through it. (add/remove elements) – matszwecja Sep 14 '22 at 06:46

It is happening, because the first time i is pointing towards the first element, it removes 12, now i increases and points to the second element, and the second element now is 23 and not 34, so it removes 23.
To fix this error, you can do something like:
a = [12, 34, 23]
for i in a:
a.remove(0)
print(a)

1"i becomes 2" is a bit oversimplified, though what you're trying to say is fundamentally correct… – deceze Sep 14 '22 at 06:59

Yes, Thank You, actually I was just trying to explain it in simple words, it should be i refers to the 2nd element, right? – Shaurya Goyal Sep 14 '22 at 07:16
