##　pre-training data
You need to manually combine each dataset if you want to use a multilingual dataset.
```python
from datasets import load_dataset
xcsn_pt_python_en = load_dataset("ynklab/XCodeSearchNet", data_dir='pretraining/python/en')
"""
DatasetDict({
    train: Dataset({
        features: ['function_tokens', 'docstring'],
        num_rows: 453623
    })
    validation: Dataset({
        features: ['function_tokens', 'docstring'],
        num_rows: 4596
    })
    test: Dataset({
        features: ['function_tokens', 'docstring'],
        num_rows: 45283
    })
})
