Started learning Python yesterday; I know little more than what is here, below. The random generator functions but the same number applies to each entry. Could someone show me how to generate a unique number for each entry (one, two, three)? Thank you. Code so far: import random number_gen = r…

[image] Rob: they wanted a unique number not a random number those are different things uuid4 doesn’t guarantee uniqueness.

be more specific about what level of uniqueness your referring to.

[image] Rob: be more specific about what level of uniqueness your referring to No, YOU be more specific about how uuid4 is better than random. You necro’d a thread to tell people to avoid the random module. Without good justification, that’s FUD and has no value to anyone.

The reason to use uuid over random is that it handles correctly seeding the generator and ensuring that you have a wide enough keyspace to provide a sufficient level of randomness that in the majority of practical use cases you should never experience a collision. I asked you what level of uniquene…

It’s not FUD, That requires deliberate malicious intent, I’m repeating what I’ve been taught and I’m thinking I’ve been mislead. How would you approach this using random?

[image] Rob: It’s not FUD, That requires deliberate malicious intent, I’m repeating what I’ve been taught and I’m thinking I’ve been mislead. You are spreading FUD and I’m calling it like it is. If you repeat what you were told without checking it, then you may not have invented it, but it’s …

While unlikely, it’s possible for the Mersenne Twister to fall into states where it gets the same 32-bit output hundreds of times in a row. A much simpler solution to get unique ints: >>> import itertools >>> getid = itertools.count().__next__ >>> getid() 0 >>> getid() 1 >>> getid() 2 >>> getid() …

[image] Chris Angelico: Probably just random.randrange(some_big_number) if I want randomly generated IDs. They’ll usually be good enough, and certainly they’ll be no worse than UUID4 if you pick a number that’s 2**128 or higher. But if I actually care about uniqueness, I have a central broker - …

Awesome. Thank You for correcting me.

Perhaps we have a different defination of the word, to me FUD is spreading misinformation to cause harm or manipulate people. I’m happy to admit I was wrong and the material effect is similar but I had no intention of causing harm. Throwing insults about just makes things toxic.

I’m genuinely sorry for wasting your time, but it seems unreasonable to ascribe malice to my ignorance
