Use consistent Python naming conventions to improve code readability and maintainability:

1. Use snake_case for functions and variables: ```python

   Bad

   def setifnotnone(dic, key, value):

Good

def set_if_not_none(dic, key, value):

2. Choose descriptive, semantic names that reflect purpose:
```python
# Bad
lst = []  # unclear what this list tracks

# Good
calls = []  # clearly indicates list tracks function calls

1. Maintain consistent naming with established patterns:
   • Use standard type names (e.g., ‘Attributes’ instead of ‘dict’ for typed parameters)
   • Follow existing naming patterns in the codebase (e.g., ‘trace_exporter’ vs ‘span_exporter’)
   • Use semantic names that align with specifications and documentation
2. For internal/private variables, use single leading underscore and consistent suffixes: ```python

   Bad

   self.currentValue = None self.previous_cumulative_value = None

Good

self._value = None self._previous_value = None ```
