| # Python Comprehension Statements 1K |
|
|
| This dataset contains 1,000 Python statements extracted from `bigcode/the-stack` |
| that include at least one Python comprehension expression: |
|
|
| - list comprehensions |
| - set comprehensions |
| - dict comprehensions |
| - generator expressions |
|
|
| Each row is a nearest enclosing Python statement around one or more |
| comprehension expressions, along with line number information and source |
| metadata copied from the original The Stack sample. |
|
|
| ## Dataset Details |
|
|
| - **Dataset name:** `py_comprehension_statements_1k` |
| - **Rows:** 1,000 |
| - **Split:** `train` |
| - **Source dataset:** `bigcode/the-stack`, Python subset |
| - **Extraction script:** `scripts/collect_stack_comprehension_statements.py` |
| - **Original local JSONL:** `outputs/the_stack_python_comprehension_statements.jsonl` |
|
|
| ## Schema |
|
|
| | Field | Type | Description | |
| | --- | --- | --- | |
| | `index` | `int64` | Zero-based index of the streamed source sample. | |
| | `statement_id` | `int64` | Statement index within the source sample. | |
| | `statement` | `string` | Extracted Python statement containing a comprehension. | |
| | `lineno` | `int64` | Starting line number in the original source file. | |
| | `end_lineno` | `int64` | Ending line number in the original source file. | |
| | `comprehension_types` | `list[string]` | AST comprehension node types present in the statement. | |
| | `metadata.hexsha` | `string` | Source commit hash from The Stack metadata. | |
| | `metadata.max_stars_repo_name` | `string` | Repository name from The Stack metadata. | |
| | `metadata.max_stars_repo_path` | `string` | File path from The Stack metadata. | |
| | `metadata.lang` | `string` | Source language label. | |
|
|
| ## Comprehension Type Counts |
|
|
| The `comprehension_types` field can contain multiple values for a single row. |
| Across the 1,000 rows, the type occurrences are: |
|
|
| | Type | Count | |
| | --- | ---: | |
| | `ListComp` | 754 | |
| | `GeneratorExp` | 181 | |
| | `DictComp` | 76 | |
| | `SetComp` | 9 | |
|
|
| ## Usage |
|
|
| ```python |
| from datasets import load_dataset |
| |
| dataset = load_dataset("nexround/py_comprehension_statements_1k") |
| train = dataset["train"] |
| |
| print(train[0]["statement"]) |
| print(train[0]["comprehension_types"]) |
| ``` |
|
|
| If you have the dataset saved locally with `datasets.save_to_disk`, use: |
|
|
| ```python |
| from datasets import load_from_disk |
| |
| dataset = load_from_disk("outputs/the_stack_python_comprehension_statements_hf_dataset") |
| ``` |
|
|
| ## Construction |
|
|
| The extraction process streamed Python files from The Stack, parsed each source |
| file with Python's `ast` module, found `ListComp`, `SetComp`, `DictComp`, and |
| `GeneratorExp` nodes, and saved the nearest enclosing statement for each unique |
| statement span. |
|
|
| Rows that could not be parsed as Python source were skipped. |
|
|
| ## Intended Uses |
|
|
| This dataset is intended for lightweight analysis and experimentation around |
| Python comprehension syntax, such as: |
|
|
| - inspecting comprehension usage patterns |
| - evaluating code models on comprehension-heavy snippets |
| - constructing small probes or prompts involving Python comprehensions |
|
|
| ## Licensing |
|
|
| This is a derived sample from The Stack. The original source code snippets come |
| from many upstream repositories with varying licenses. Users should consult and |
| respect the licensing metadata and terms of the upstream The Stack dataset and |
| the original repositories when using or redistributing examples. |
