python 用codecs实现数据的读取

import numpy as np

import codecs

f=codecs.open('testsklearn.txt','r','utf-8').readlines()

print(f)

dataset=list()

for i in f:

    list_data= i.split(',')

    List=list();

    for j in list_data:

        data=float(j)

        List.append(data)

    dataset.append(List)

dataset1=np.array(dataset)

print(type(dataset1))

X = dataset1[:,0:7]

y = dataset1[:,8]
