THIS Python Module Will Make Your Users More UNIQUE!

THIS Python module will make your users more unique! #Python. #code

My paranoid ass would check for that collision even with <10 users.

So when I have 2.7 quantillion users, I will have the problem with duplicate identifiers? Bad

[matthewbrough]

should probably consider using inbuilt functionality in a database for things like this to avoid conflicting ids

[alxjones]

The UUID should really be the key, since the whole idea of dictionaries is that the key is unique while the value may not be. Right now, if a new user is named Mario, it would just overwrite the first Mario. If you make the ID the key, then generate a new key for every new user, you can have two different users named Mario with separate IDs.

If you don't want users to have name collisions, i.e. you require user names to be unique, then you make that guarantee on creation and so the user name *becomes* the unique ID, eschewing the need for UUID in the first place.

Actually, depending on the condition it can be as low a 1 in 65536. If you are generating multiple uuid at the same time on the same machine, you have a 1 in 65536 of having a collision, since the actual random part is 16 bits long and the rest is generated by the time stamp and some elements identifying the machine.

[ramialz]

Used it last time but, the IDs so crazy long, do you know any other ways?

[climatechangedoesntbargain]

"but it would be much better"

No, it would not.
UUIDs aren't truly unique, need more memory and are slower (usually).

I've been using it for a while.
The new thing I learned this short is the sep=
Game changer for debugging multiple values bc I can comma seperate them!

[jeodazang]

this uuid is best for database auto id something like that :-) when having large data

[Jugularst]

So they're not gauranteed unique... seems poorly named.

[cyberdaniboy]

What I don't understand is why should I be risking this 1 in quintillion chance, when there is no such risk with incremental IDs. I guess it only makes sense if I'm using with small amount of disposable data to lower the amount of stuff you write.

[sushileaderyt]

All great until you generate the same uuid

[ArmaganSalman]

What if no collision guarantee is required?

[greycell]

Except I'm a Libra... guaranteed collision.
