Yes, but there are people -- I've encountered them! -- who look on this as a way to show how "clever" they are, and consider it a good thing.

It's like Perl golf take to an extreme.

(admittedly, some of my co-workers and I have been known to golf our interview questions into ridiculous one-liners, but we do it for amusement value, not because we'd ever write production code that way)

It's a reaction to the Perl community, which whom Python once competed. Perl programmers absolutely loved writing very clever "one liner" programs (look up Perl Golf). Python programmers therefore took pride in writing code that wasn't "clever."
