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.

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
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:
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.
