from sklearn import preprocessing
data = preprocessing.scale(values) #注意，这里的values是array

Z-Score数据标准化处理（python代码）

#/usr/bin/python
 
def Z_Score(data):
    lenth = len(data)
    total = sum(data)
    ave = float(total)/lenth
    tempsum = sum([pow(data[i] - ave,2) for i in range(lenth)])
    tempsum = pow(float(tempsum)/lenth,0.5)
    for i in range(lenth):
        data[i] = (data[i] - ave)/tempsum
    return data
 
print Z_Score([2,2,3,4,5,6,7,8])
print Z_Score([10,20,30,40,50,60,70,80])
print Z_Score([20,20,30,40,50,60,70,80])
