摘 要：We introduce ACES--Automated Coding Evaluation of Style--a module that automates grading for the composition of Python programs. ACES, given certain constraints, assesses the composition of a program through static analysis, conversion from code to an Abstract Syntax Tree, and clustering (unsupervised learning), helping streamline the subjective process of grading based on style and identifying common mistakes. Further, we create visual representations of the clusters to allow readers and students understand where a submission falls, and what are the overall trends.
