Sorry, but you seem unable to see why people like Python (or a different language X). Until you see that, you won't understand why job postings are written like that.
This is not to say Python (or X) is a perfect language or that you have to agree with those that like it - it's just not your language.
I don't agree. I've been ridiculously in love with a few languages over the years, but it's a passing phase. The more you get to know something the more design compromises etc you see.
No language is perfect, but Clojure is the best designed I think I've come across. I really like it, more than any other (including a few years of Python which I 'liked' at the time). It has strengths and weaknesses though, and that's expected of anything.
"Ridiculously in love with" is recruitment fluff, but I think does have the side-effect of appealing to that temporary experience, or to people prone to hyperbole.
Ah, but that's fine regarding the recruitment fluff.
The question above carries the assumption that one can't be "ridiculously in love" with a programming language because "if only they knew better" they'd realise the flaws of the language (whether that's specifically Python or a different language).
But that's inherent to any programming language - it'll be good for some things and bad for others - using the phrase "ridiculously in love" just means they're looking for someone who likes working in that language.
