**Additional practical example showing index and columns rename:**

>>> df = pd.DataFrame({"X": [1, 2, 3], "Y": [4, 5, 6]}, index=["a", "b", "c"])
>>> df.rename(columns={"X": "new_X", "Y": "new_Y"},

**Using a function to transform column names:**

>>> df = pd.DataFrame({"X": [1, 2, 3], "Y": [4, 5, 6]}, index=["a", "b", "c"])
>>> df.rename(columns=str.lower, index=lambda x: x.upper())
