Python is just fastest to write. No semicolons, fewer parens, no braces, no const / var / let. List / dict / set comprehensions. Lambdas are clunkier, but `def` is shorter than `function`. Etc.

Perl and Ruby are comparably compact and expressive, but relatively few people know Ruby, end even fewer people know Perl, especially among those younger than 50.

BTW Haskell is also syntactically compact and expressive; I once solved a toy interview problem using it. But even fewer people know it at a practical level, among interviewees and interviewers alike.
