# Sample Realistic Data

Create realistic synthetic data data that follows the same format and mathematical properties as the real data.

### sample

Use this function to create synthetic data that mimics the real data

```python
synthetic_data = synthesizer.sample(
    num_sequences=100,
    sequence_length=None
)
```

**Parameters**

* (required) `num_sequences`: An integer >0 describing the number of sequences to sample
* `sequence_length`: An integer >0 describing the length of each sequence. If you provide `None`, the synthesizer will determine the lengths algorithmically, and the length may be different for each sequence. Defaults to `None`.

**Returns** A [pandas DataFrame](https://pandas.pydata.org/docs/reference/api/pandas.DataFrame.html) object with synthetic data. The synthetic data mimics the real data.
