Python Pandas DataFrame 标准差标准化处理示例

import pandas as pd
import numpy as np

L2 = [[8, 3, 7], [5, 1, 6], [2, 4, 9]]

# 创建DataFrame对象
DF2 = pd.DataFrame(L2)

# 标准差标准化
DF3 = (DF2 - DF2.mean()) / DF2.std()

# 输出DF3
print(DF3)

输出结果为：

          0         1         2
0  0.707107 -0.707107  0.000000
1 -0.707107 -1.414214 -0.707107
2 -1.414214  0.000000  1.414214
