python读取csv和txt数据转换成向量的实例

import csv
 
filtpath = "data_test.csv"
 
with open(filtpath,'r') as csvfile:
  reader = csv.reader(csvfile)
  header = next(reader)
  data = []
  for line in reader:
    data.append(line)
  print(header)
  print(data) 

import numpy as np
 
#load data
file=open("data.txt")
lines=file.readlines()
rows=len(lines)
 
datamat = np.zeros((rows,15))
 
row=0
for line in lines:
  line=line.strip().split('\t')
  datamat[row,:]=line[::]
  row+=1
 
print(datamat)
print(datamat.shape)
