Use Type Hints\n\nPython 3.5+ supports type hints.

Use List Comprehensions Wisely\n\nList comprehensions are concise and efficient, but excessive complexity reduces readability. Keep them simple and clear.\n\n```python\n# Good practice\nsquares = [x**2 for x in range(10)]\n\n# Avoid\nresult = [(x, y, x*y) for x in range(10) if x % 2 == 0 for y in range(5) if y > 2]\n```\n\n## 4. Use Context Managers for Resource Handling\n\nUse the `with` statement to automatically manage the opening and closing of files or other resources.\n\n```python\nwith open('file.txt', 'r') as f:\n    content = f.read()\n```\n\n## 5. Avoid Mutable Default Arguments\n\nMutable objects as default arguments can lead to unexpected behavior.\n\n```python\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\n## 6. Use Virtual Environments\n\nCreate independent virtual environments for each project to manage dependencies and avoid version conflicts.\n\n## 7. Write Docstrings\n\nWrite 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\nPython 3.6+ recommends using f-strings, which are faster and more readable than `%` formatting and `.format()`.\n\n```python\nname = \"Alice\"\nprint(f\"Hello, {name}!\")\n```\n\n## 9.
