The Series name can be set initially when calling the constructor.

s = pd.Series([1, 2, 3], dtype=np.int64, name='Numbers') s 0 1 1 2 2 3 Name: Numbers, dtype: int64 s.name = "Integers" s 0 1 1 2 2 3 Name: Integers, dtype: int64

df = pd.DataFrame([[1, 2], [3, 4], [5, 6]], ... columns=["Odd Numbers", "Even Numbers"]) df Odd Numbers Even Numbers 0 1 2 1 3 4 2 5 6 df["Even Numbers"].name 'Even Numbers'
