Why must the set seed instruction and the random draws be in the same cell in Jupyter? 10

anoldmaninthesea anoldmaninthesea

3 A pseudo-random number generator can be modelled as an infinite stream of bits. Every time you generate a number using the pseudo-random number generator, it shifts the stream along, returning and discarding the bits at the beginning. Seeding the PRNG discards the current stream and selects the one specified by the seed.

They are all good thoughts — and mostly applicable in other communities too. I guess an answer that's useful for future users is one that explicitly draws out a principle of good coding, so we have to hope that that is the way people will vote in practice

So good to see you! (Well, "see" you!) I'm a bit disappointed in @Jack who seems not to have cracked your cyber-identity. 😅 Hope you can stick around, and have some fun in the other "areas", too. :+1:

Good morning/afternoon/evening! Just wanted to share this incredible, high-quality, free learning resource on Python Data Science I discovered over the weekend: https://www.kaggle.com/learn/overview 🤓

Thanks for this, Pax. Would it be suitable, do you think, for someone who has just dabbled in PHP? I would like (in my amateur way) to learn some Python, though, and this might be a good way in. Thoughts?
