[Tutor] reg. list update

[Rasika Sapate]

Dear Python group,
I had written following code.

super = []
sub = [""]*3
other = ["a","b","c","d"]
sub[0] = "hi"
sub[1] = "hello"
for item in other:
    sub[2] = item
    super.append(sub)
for item in super:
    print item


Output :
['hi', 'hello', 'd']
['hi', 'hello', 'd']
['hi', 'hello', 'd']
['hi', 'hello', 'd']


Expected output:
['hi', 'hello', 'a]
['hi', 'hello', 'b']
['hi', 'hello', 'c']
['hi', 'hello', 'd']


Is there anything wrong in this code or any feature of python?

Thanks and regards,
Rasika Sapate.
