# NPset
A normalized semi-sythetic Python dataset for training small language models on code logic without the overhead of raw code syntax.
## Why
Small language models trained on natural language corpora develop latent representations of logical constructs -- iteration, conditionals, data flow, function composition -- yet struggle to apply this reasoning to source code, where syntactic overhead (delimiters, indentation conventions, language-specific idioms) occupies a disproportionate share of the token budget, requires a vocabulary of code-specific tokens rarely encountered during pretraining, and introduces a surface-form distribution shift relative to the model's prior knowledge. NPset addresses this by normalizing Python source through an AST-based converter that strips syntactic noise while preserving the full logical structure of each program, producing a pseudocode representation composed entirely of natural language tokens that aligns more directly with the semantic representations already present in small models, allowing them to reason about what code *does* rather than expending capacity learning what it *looks like*.
## Format
Parquet, shuffled. Each row:
| Field | Type | Description |
|---|---|---|
| `code` | string | Normalized pseudocode |
| `original_code` | string | Original Python source |
| `original_language` | string | Always `Python` |
| `source` | string | Origin dataset identifier |
