Yikes! - someday soon I am going to read the docs on what reduce does...
Reduce just intersperses an operator over a sequence. For example,
reduce(operator.add, (a,b,c,d,e))
is a+b+c+d+e.
Won't this be slow

No, wait! Use the feared UDPLUD code.
You go Ubbi Dubbi to Pig Latin, and then Ubbi Dubbi again.

You could use the mult127 function, self-inverting like its better
known but more easily

For extra security, you can encode the string with rot13 twice.

It's a lot faster. Sometimes that matters.

For a short string like Python, using an array is a tiny bit slower, at
the cost of more complex code if you're converting a long string,
using array is faster. If it is a short string, it doesn't make much
difference.
