# Sampler Parameters

The `sampler_params` module defines parameter configuration objects for all Data Designer sampler types. Sampler parameters are used within the [SamplerColumnConfig](/code-reference/config/column-configs#data_designer.config.column_configs.SamplerColumnConfig) to specify how values should be generated for sampled columns.

Displaying available samplers and their parameters
The config builder has an `info` attribute that can be used to display the
available sampler types and their parameters:

```python
config_builder.info.display("samplers")
```
