I thought the reason why "Python is 2nd best" isn't primarily its syntax, but the libraries which are available to use (and big enough communities using them).

I thought the reason why "Python is 2nd best" isn't primarily its syntax, but the libraries which are available to use (and big enough communities using them). e.g. with Python you can find libraries (and decent tutorials/examples) for: a small or big web framework, computer-vision, data-science / reproducible science, machine-learning, natural language processing, web-scraping or website testing.
