OptionalProvider uses existent faker providers to create the data, so you can use the provider method arguments. For example, optional_int uses the python provider pyint, so you can use the min_value, max_value, and step arguments. Every optional_ method accepts the float ratio argument between 0 and 1, with a default value of 0.5 to define what percent of results should be None, a greater value will mean that less results will be None.

Learn to use Python Faker's random data generator to generate data for testing & development. Configure the fake data generator so it does not use dummy data in production.

June 16, 2021 - Use random() and uniform() functions to generate a random float number in Python. Get random float number with two precision. Use Numpy.random to generate a random array of float numbers.

Behaviour that defines randomisation in faker. random_between(integer, integer) random_bytes(pos_integer) random_uniform() Link to this callback · View Source · @callback random_between(integer(), integer()) :: integer() Link to this callback · View Source · @callback random_bytes(pos_integer()) :: binary() Link to this callback · View Source · @callback random_uniform() :: float()

For a simple random true or false value, use boolean(). Returns the boolean value true or false. Note: A probability of 0.75 results in true being returned 75% of the calls; likewise 0.3 => 30%. If the probability is <= 0.0, it will always return false. If the probability is >= 1.0, it will ...
