计算pandas dataframe行中列表的平均值和标准dev

import pandas as pd

data = {'A': [1, 2, 3, 4, 5],
        'B': [6, 7, 8, 9, 10],
        'C': [11, 12, 13, 14, 15]}
df = pd.DataFrame(data)

row_mean = df.mean(axis=1)

row_std = df.std(axis=1)

for i in range(len(df)):
    print("Row", i+1, "mean:", row_mean[i])
    print("Row", i+1, "std:", row_std[i])
