That is an astonishing claim for you to assert without evidence.
Python's PRNG is the Mersenne Twister, which is one of the most heavily

While FWIU it is advisable to keep seeding an RNG after startup - that's
what e.g. rngd does - the cryptography.io docs do advise to just use

I am an amateur enthusiast. The random function I found in documentation
was in 2014 or so. I do not have the vocabulary to differentiate between
various prng's. I only knew of one, and I it returned some version of the
bell curve, with three favorite values, and one of THEM a pronounced
preference

No no, here is absolutely fine :) Although the code you posted doesn't

First the good news: your random number genera

Better is what way? What do you think the current MT PRNG lacks?

That list teaches a vocabulary in which to speak about randomness. Since my

Thanks! (I was ignorant; reinventing the wheel if mine is adequate)
