5 Random Useful Python Functions

[@chyldstudios]

This video is choice(['cool', 'amazing', 'random'])

[@__christopher__]

Replace choice with sample of size 3

[@joshix833]

__import__("random").Random(42).choice(("worst", "worse", "bad", "good", "better", "best"))

[@nextisnowmain]

Amazing ❤

[@williamsquires3070]

Hint: if you need a list of unique random integers, you combine the list comprehension that generates an ordered list from (x,y), and then call shuffle() on it, where x < y and are integers. 😊

[@basurigos]

Hey man, your videos are amazing, could you please make a video about how the built in functions work under the hood, like how does __import__ or __build_class__ work, i know those are do not touch functions, but I'm curious

[@Russet_Mantle]

7:51 the words you're looking for are "with replacement" (choice) and "without replacement" (sample) as in statistics lingo

[@souris_a_boule5695]

Something that can be interesting is to use the Random class from this module. It provide exact same functions as method but each instance have its own seed and and are not shared with the global seed. So for example you can use this in a class that have random behavior where each instances have their own seed and each random function call will not affect another instance

[@danielcrompton7818]

Thank you!😊

[@davidmurphy563]

Ok, I was into the third function before the penny dropped and I twigged you were covering the `import random` module and not just going through random functions!

[@killerfc]

🤣 me too

[@Indently]

It was a silly wordplay with the title, I hope you enjoyed the video though! :)

[@davidmurphy563]

@@Indently Yeah, it was good! I like your vids. Well, I knew it already but, I'm sure many don't and I watch just in case. :)

[@danielcrompton7818]

@@Indentlyyes I get the joke now!!

[@sovereignlivingsoul]

good coding practices, that is what i like to learn, thanks for your input

[@dipeshsamrawat7957]

Nice! Keep it up. 💯

[@69k_gold]

Does choices() always guarantee that we won't get the element at the same index twice if we call it with a number less than len(list)

[@k.r.jester5406]

No, if you want that you should use random.sample()

[@yash1152]

8:48 shuffle vs sample can trip over many ppl many times ig

Do you think there's a way to reverse engineer randomness using seed in some way?

[@hindsighttt]

im pretty sure there is but you gotta look at the code of the random library and do it that way

[@DendrocnideMoroides]

There definitely is, if you want a more secure version of the random library then use the secrets library in Python.

[@katrinabryce]

Yes, and a lot of security work goes in to making sure people aren't able to do that. Cloudflare for example use a bunch of lava lamps to generate their random seed.

[@Reojoker]

Seed is also useful if you write software for research as it allows your results to be easily reproducible.

[@paulosergioschlogl9550]

nice video. thanks

[@dbottesi]

Another great video!! Thumbs 👍

[@danielcrompton7818]

Hey, will you make any more iOS videos, that is actually how I found your channel!!! I also program in Python so your videos are still really interesting

[@sadhappy8860]

I knew about choices but sample would have been really helpful about a year ago

[@Pawlo370]

how to know seed?

[@danielcrompton7818]

Make it up! It doesn’t matter what it is, just so long as it is consistent for the best results

[@winTer_x64]

More flet tutorials plzzz

[@michaelhoffmann2891]

Addendum: do NOT use any of these for cryptographic, or even scientific, code! 😆

[@tinahalder8416]

In ML to randomise data, these functions are used. For crypto there is secure module

[@alboz1327]

Why wouldn't I use these for sci programming... I can always specify a seed anyway, to make experiments testable. I would be interested if you wanted to give more insights into what you are saying, thanks!

i have applied for coupoun code please provide me it is so much helpful for me
