  • Clarifies the behavior when using Python lists in arithmetic operations with DataFrames.
  • Adds an example in dsintro.rst to show how adding a list returns a Series of arrays.
  • Adds a note in basics.rst to explain that lists are not broadcasted element-wise, unlike NumPy arrays or Series.
  • Fixes DOC: improve docs for broadcasting behavior #18857.

df = pd.DataFrame(np.arange(6).reshape(2, 3), columns=["A", "B", "C"])
df + [1, 2, 3] # Returns a Series of arrays, not a DataFrame
