python读写文件合集

1、读.mat文件
import scipy.io as scio
import numpy as np
path = “.mat”
data = scio.loadmat(data)
#如果.mat里包含多个变量，如seq_m何lab_m
x1 = np.asarray(data[‘seq_m’])
y1 = np.ravel(data[‘lab_m’])

2、读.csv文件
import pandas as pd
path = “.csv”
data = pd.read_csv(path)
dataset = data.as_matrix()
#从.csv文件中选取部分作为x和y
dataset_x = dataset[:, 1:]
dataset_y = dataset[:, 0]
