Longer, but the probability of a collision will still be very low. ![]() Truncating the string to the desired length. If the default 22 digits are too long for you, you can get shorter IDs by just Shortuuid will automatically sort and remove duplicates from your alphabet to ensureĬonsistency: > shortuuid. uuid () '0agee20aa1hehebcagddhedddc0d2chhab3b' set_alphabet ( "aaaaabcdefgh1230123" ) > shortuuid. If you want to use your own alphabet to generate UUIDs, use set_alphabet(): > shortuuid. get_alphabet () '23456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz' To see the alphabet that is being used to generate new UUIDs: > shortuuid. ![]() random ( length = 22 ) 'RaF56o2r58hTKT7AYS9doj' You can also generate a cryptographically secure random string (using os.urandom() uuid ( name = "" ) 'shortuuid.uuid(name="")' uuid ( name = "" ) 'exu3DTbj2ncsn9tLdLWspw' > shortuuid. If you prefer a version 5 UUID, you can pass a name (DNS or URL) to the call and it willīe used as a namespace ( uuid.NAMESPACE_DNS or uuid.NAMESPACE_URL) for the resulting You can then generate a short UUID: > shortuuid. To use shortuuid, just import it in your project like so: > import shortuuid To install the source, download it from.With setuptools, do easy_install shortuuid.With pip (preferred), do pip install shortuuid.If you have the dependencies, you have multiple options of installation: Generating uuids using Python's built-in uuid module and then translating them toīase57 using lowercase and uppercase letters and digits, and removing similar-looking IDs must be as concise and easy to use as possible. Often, one needs to use non-sequential IDs in places where users will see them, but the Overriding the given 'hex', 'bytes', 'bytes_le', 'fields', or 'int'.Shortuuid is a simple python library that generates concise, unambiguous, URL-safe UUID will have its variant and version set according to RFC 4122, The 'version' argument is optional if given, the resulting Hyphens, and a URN prefix are all optional.

(Or achieve this by some other means)? What I've tried so far I would like to be able to generate the same random UUID every time I run a script - that is, I'd like to seed the random generator in uuid4(). The uuid4() function of Python's module uuid generates a random UUID, and seems to generate a different one every time: In : import uuid
