8、特征选择

用过滤法对以下数据进行特征选择：

                             [[0,2,0,3],

                              [0,1,4,3],

                              [0,1,1,3]]

要求：

1、Variance Threshold（threshold =1.0）

2、将结果截图

from sklearn.feature_selection import VarianceThreshold

def var():

    var = VarianceThreshold(threshold = 1.0)

    data = var.fit_transform([[0,2,0,3],[0,1,4,3],[0,1,1,3]])

    print(data)

    return None

if __name__ == "__main__":

    var()
