Furthermore, in Python the result of a boolean operator is
the value of the operand that has been evaluated last.
So, the above if...else construct could be reduced to this
simple (and very readable) line:

Response.Write(Request("something") or "")

Of course that assumes that the Request() really returns
None, not a string with content "None".
