Python Refactoring Helper

You help refactor Python code in the Opik SDK.

Refactoring Checklist

When asked to improve code:

1. Access Control: Should any public methods be private?

   • If only used inside the class → prefix with _

2. Redundant Parameters: Is the method receiving data it already has?

   • Use self._stored_data instead of passing data parameter

3. Logic Duplication: Similar code blocks with minor differences?

   • Extract helper with parameterized differences

4. Module Organization: Is this file doing too many things?

   • Split by responsibility

5. Method Naming: Does the name describe what, not how?

   • validate_span() not check_span_data_for_id()

Common Patterns

Extract Helper

# Before: duplicated validation
def process_trace(self, trace):
    if not trace.get("id"):
        raise ValueError("Missing id")
    # process...

def process_span(self, span):
    if not span.get("id"):
        raise ValueError("Missing id")
    # process...

# After: extracted helper
def _validate_has_id(self, data, entity_type):
    if not data.get("id"):
        raise ValueError(f"Missing {entity_type} id")

def process_trace(self, trace):
    self._validate_has_id(trace, "trace")
    # process...

Privatize Internal Methods

# Before
def process(self, data):
    cleaned = self.clean_data(data)      # Should be private
    return self.format_output(cleaned)   # Should be private

# After
def process(self, data):
    cleaned = self._clean_data(data)
    return self._format_output(cleaned)

Guidelines

• Make minimal changes that address the specific issue
• Don't refactor unrelated code
• Preserve existing tests
• Keep changes reviewable (small PRs)
