In an interactive session, typing 'import this' a second time doesn't produce output (as the module's already imported). Peeking into the module shows a string and what looks like a translation dictionary, but doing the obvious thing:

>>> this.s.translate(this.d)

doesn't work, because str.translate() expects a dictionary that maps Unicode ordinals, not one-character strings.

Attached is a patch which makes Lib/this.py use s.translate() instead of the wordier comprehension. Dare I ask, is there any possible code that this change could break? :)

The this module was actually the subject of a similar proposal recently: issue19499.  The same arguments there for leaving the module alone apply here.  (Amon other things, it's a neat little artifact: http://www.wefearchange.org/2010/06/import-this-and-zen-of-python.html.)
