Random name and slug generator

Project description

pypi build status coverage documentation

Do you want random human-readable strings?

>>> from coolname import generate_slug
>>> generate_slug()
>>> generate_slug()
>>> generate_slug()


  • Generate slugs, ready to use, Django-compatible.

    >>> from coolname import generate_slug
    >>> generate_slug()
  • Generate names as sequences and do whatever you want with them.

    >>> from coolname import generate
    >>> generate()
    ['beneficial', 'bronze', 'bee', 'of', 'glee']
    >>> ' '.join(generate())
    'limber transparent toad of luck'
    >>> ''.join(x.capitalize() for x in generate())
  • Generate names of specific length: 2, 3 or 4 words.

    >>> generate_slug(2)
    >>> generate_slug(3)
    >>> generate_slug(4)

    Note: without argument, it returns a random length, but probability of 4‑word name is much higher. Prepositions and articles (of, from, the) are not counted as words.

  • Over 1010 random names.













    >>> from coolname import get_combinations_count
    >>> get_combinations_count(4)
  • Hand-picked vocabulary. sexy and demonic are about the most “offensive” words here - but there is only a pinch of them, for spice. Most words are either neutral, such as red, or positive, such as brave. And subject is always some animal, bird, fish, or insect - you can’t be more neutral than Mother Nature.

  • Easy customization. Create your own rules!

    >>> from coolname import RandomGenerator
    >>> generator = RandomGenerator({
    ...   'all': {
    ...     'type': 'cartesian',
    ...     'lists': ['first_name', 'last_name']
    ...   },
    ...   'first_name': {
    ...     'type': 'words',
    ...     'words': ['james', 'john']
    ...   },
    ...   'last_name': {
    ...     'type': 'words',
    ...     'words': ['smith', 'brown']
    ...   }
    ... })
    >>> generator.generate_slug()


pip install coolname

coolname is written in pure Python and has no dependencies. It works on any modern Python version, including PyPy.

Release history

1.0.4 (2018-02-17)

  • Breaking changes:

    • Renamed RandomNameGenerator to RandomGenerator.

    • randomize was removed, because it was just an alias to random.seed.

  • Phrase lists give you even more freedom when creating custom generators.

  • You can seed or even replace the underlying random.Random instance, see Randomization.

  • Change the default generator using COOLNAME_DATA_DIR and COOLNAME_DATA_MODULE. This also saves memory!

  • Total number of combinations = 60 billions.

For earlier releases, see History
