Break down complex logic into small, well-named functions that each do one thing well. This improves code readability, maintainability, and testability by making the code's intent clearer and reducing cognitive load. Consider this example from discussion #6: ```python # Before if "virtual_resources" in vertex.config: for i, v in enumerate(self.vertices): if v.name in vertex.config["virtual_resources"]: self.create_edge(i, origin_node_index, "virtual_resource") # After def create_virtual_resources_edges(self, origin_node_index, vertex): if "virtual_resources" in vertex.config: for i, v in enumerate(self.vertices): if v.name in vertex.config["virtual_resources"]: self.create_edge(i, origin_node_index, VIRTUAL_RESOURCE_EDGE) ``` Similarly, complex conditions should be extracted into functions with descriptive names: ```python # Before if self.bc_integration.repo_matches(file_suppression['repositoryName']) \ and (suppression_file_path == record_file_path or suppression_file_path == convert_to_unix_path(record_file_path)): # Do something # After def is_matching_suppression_path(self, file_suppression, record_file_path): suppression_file_path = normalize_path(file_suppression['filePath']) return (self.bc_integration.repo_matches(file_suppression['repositoryName']) and (suppression_file_path == record_file_path or suppression_file_path == convert_to_unix_path(record_file_path))) ``` Apply this principle to: - Similar code blocks that appear in multiple places - Complex conditional logic - Deeply nested loops or conditions - Code blocks over 5-10 lines - Logic that can be reused elsewhere This practice makes code more self-documenting and easier to test, modify, and debug.
