How many times did you need this feature recently? I don't recall
having to generate a random number in a range.

> python -m random urandom 10 => print(os.urandom(10))

I don't understand the use case. Can you elaborate?

> python -m uuid uuid4 => print(uuid.uuid4().hex)

FYI On Linux, you can use "cat /proc/sys/kernel/random/uuid" ;-)

I agree that -c is enough here:
./python -c 'import uuid; print(uuid.uuid4())'

> python -m uuid uuid3 => print(uuid.uuid3().hex)

I don't know UUID3. It looks like you need more parameters.

IMHO these use cases are not popular enough to justify a CLI.

hashlib CLI is inspired by existing tools: md5sum, sha1sum, etc. Same
rationale for Python tarfile CLI. What are the existing commands which
inspired your CLI?
