Merge & Stack example is incorrect

[reza1615]

the above example should be

df1 = pd.DataFrame({
    "A": ["A0", "A1", "A2", "A3"],
    "B": ["B0", "B1", "B2", "B3"],
    "C": ["C0", "C1", "C2", "C3"],
    "D": ["D0", "D1", "D2", "D3"]},
    index=[0, 1, 2, 3]
)
df2 = pd.DataFrame({
	"A": ["A4", "A5", "A6", "A7"],
	"B": ["B4", "B5", "B6", "B7"],
	"C": ["C4", "C5", "C6", "C7"],
	"D": ["D4", "D5", "D6", "D7"]},
	index=[4, 5, 6, 7],
)
df3 = pd.DataFrame({
	"A": ["A8", "A9", "A10", "A11"],
	"B": ["B8", "B9", "B10", "B11"],
	"C": ["C8", "C9", "C10", "C11"],
	"D": ["D8", "D9", "D10", "D11"]},
	index=[8, 9, 10, 11]
)
result = pd.concat([df1, df2, df3])
