\n\n 5. Avoid Mutable Default Arguments
\n Mutable objects as default arguments can lead to unexpected behavior.
\n # Avoid\ndef add_item(item, items=[]):\n items.append(item)\n return items\n\n# Recommended\ndef add_item(item, items=None):\n if items is None:\n items = []\n items.append(item)\n return items
\n\n 6. Use Virtual Environments
\n Create independent virtual environments for each project to manage dependencies and avoid version conflicts.
\n\n 7. Write Docstrings
\n Write clear docstrings for functions, classes, and modules to describe their purpose, parameters, and return values.
\n\n 8. Use f-strings for String Formatting
\n Python 3.6+ recommends using f-strings, which are faster and more readable than % formatting and .format().
\n name = \"Alice\"\nprint(f\"Hello, {name}!\")
\n\n 9. Be Precise with Exception Handling
\n Catch specific exception types, avoid bare except clauses, and ensure error information is traceable.
