# Python Docstring Diff Dataset

This dataset contains training samples for models that generate Python documentation patches.
Each example provides a Python source file with its docstrings removed and a corresponding unified diff patch that restores the documentation.

The dataset is designed for training or evaluating language models that assist with:

* Automatic code documentation
* Docstring generation
* Code review automation
* Developer tooling
* Dataset Structure

Each entry contains the following fields:

Field	Description
-------------------
instruction|	Task instruction given to the model
code|	Python source code with docstrings removed
response|	A unified diff patch that adds the correct docstrings
file|	Original file path from the source project

## Task Format

The model receives a Python file missing its documentation and must produce a unified diff that adds appropriate docstrings.

Example input:

```python
def load_json(path):
    with open(path) as f:
        return json.load(f)
```

Example expected output:
```diff
--- a/file.py
+++ b/file.py
@@
 def load_json(path):
+    """Load JSON data from a file path."""
     with open(path) as f:
         return json.load(f)
```

## Data Sources

The dataset was generated by scanning Python packages in github.
Docstrings were extracted from functions, classes, async functions, methods, and modules using Python's AST parser.
Low-quality documentation was filtered out using heuristics such as:

* Minimum docstring length
* Removal of TODO or placeholder documentation
* Deduplication of similar examples

## Intended Use

This dataset is useful for training models that perform:

* automatic docstring generation
* documentation patch creation
* codebase documentation improvement tools
* AI-assisted code review systems
