If one really wants to write this as a one-liner in Python, it's
probably best written using Haskell-like list comprehensions:

''.join([chr(ord(x)^42) for x in tuple('zS^BED\nXEIAY\x0b')])

which is pretty idiomatic Python.

I'll cite Fredrik Lundh's insights on (over)using lambdas:

here's the eff-bot's favourite lambda refactoring rule: 
1) write a lambda function
2) write a comment explaining what the heck that lambda does
3) study the comment for a while, and think of a name that captures
   the essence of the comment
4) convert the lambda to a def statement, using that name
5) remove the comment
