I have a question about “None”. This exercise says
None is a special value in Python. It is unique (there can’t be two different
None s) and immutable (you can’t update
None or assign new attributes to it)."
So I thought it would be error
aa = None
aa = “something”
#end of code
When I ran codes, The result was
I didn’t get error and I thought I did assign new attributes to “aa” which was “None”.
Why is None immutable ?
