Even if it is homework, I think this is a good post:
- the OP posted his code that he had written so far
- the OP asked a specific question (how to write "1#2#3"), not just
"help! it wont work! fix it for me!"

To the OP:
If you can get your data into a list of values, ['1', '2', '3'], then
use the join method to join them together with a separator string:

print "#".join(['1', '2', '3'])

gives:

1#2#3
