I find python by far my favorite language to have used, but I basically agree with this. No language is perfect for every use, nor could there ever be such a language (until computing changes dramatically, anyway; quantum computing maybe?)

Until then, even a language one loves deeply - and I'm not sure I'm there yet with python, though i'm closer than with any other language I've used - will have flaws and times where it's not the best tool for the job.
