Compilation includes the following stages: 1. Tokenizing. 2. Creating CST (concrete syntax tree). 3. Creating AST (abstract syntax tree). 4. Optimizing AST. 5. Building symtable. 6. Generating bytecode. 7. Optimizing bytecode. ast.parse() only includes stages 1-3. Many warnings and errors can be raised at stages 5 and 6 (for example errors for "break" outside of a loop and "unlocal" at module level). If you want to get all warnings and errors, use compile().
