New submission from ughacks ugha...@yahoo.com:
Dear,
I am using
$ python -V
Python 2.6.4
on Ubuntu 9.10
I met a serious bug in s.append(x) operation. If I append a list into another
list, there is a change of content. In the following code, [2,-2,0,0] is
replaced with [-2,-2,0,0] after
ughacks ugha...@yahoo.com added the comment:
Thank you for kind explanation.
So s.append(x) just copies the pointer, not the actual value. It is a little
tricky to know that.
