No, it's not. Or rather it is. Depends on your own code.
Better read about it in the Language Reference,
http://www.python.org/doc/current/ref/for.html

Generally, I find it better to just iterate over a copy,
and change the original list.

Eh.. no need to search for the element in the list.
This is painfully slow.

Just write:

	x.remove("C")

if you need to remove "C" from the list x.
