Python 读取TXT文本数据并存为 array

方法一 str -> list -> array

import numpy as np
f = open(r"D:\data.txt")
line = f.readline()
data_list = []
while line:
num = list(map(float,line.split()))
data_list.append(num)
line = f.readline()
f.close()
data_array = np.array(data_list)

readline()

split()

map()

方法二 str -> array

import numpy as np
f = open(r"D:\data.txt")
line = f.readline()
data = np.zeros((100,4))
i = 0
while line:
num = np.array([float(x) for x in line.split()])
data[i,:] = num
line = f.readline()
i = i+1
f.close()
