在Python中添加平均值、中位数和标准差值作为新数组列

pip install pandas

import pandas as pd

# 创建一个示例数据框
data = {
    'Value': [10, 20, 30, 40, 50, 60, 70, 80, 90, 100]
}
df = pd.DataFrame(data)

# 计算平均值、中位数和标准差
df['Mean'] = df['Value'].mean()
df['Median'] = df['Value'].median()
df['Std_Dev'] = df['Value'].std()

# 显示结果
print(df)

   Value     Mean  Median  Std_Dev
0     10   55.0     55.0  28.7228
1     20   55.0     55.0  28.7228
