Those were your words, not mine. I need not make any assumptions.

I just replied listing use cases where Python shine due to its strengths, performance being mostly irrelevant. I didn't even mention data science.

And although it's beyond the point, if I was to use Python, why should I care in which language a library was written? If the language allows libraries written in other languages, this is actually a nice feature.
