Python3 读取文件并将 int 值的二维数组放在一行
Python3 read file and place 2D array with int value one line
我感兴趣的是这 2 行可以在 1 行中解决：
data = [ line.strip().split() for line in f ] # f = file
data = [ [ int(num) for num in nums ] for nums in data ]
文件示例行：
9 3 14 3 10 17
9 8 19 12 5 9
示例结果：
[[9, 3, 14, 3, 10, 17], [9, 8, 19, 12, 5, 9]]
尝试：
f = open("file.txt", "r")
data = [[int(num) for num in line.split()] for line in f.readlines()]
print(data)
[[9, 3, 14, 3, 10, 17], [9, 8, 19, 12, 5, 9]]
或者使用 numpy 可以稍微整洁一些：
import numpy as np
data = np.loadtxt("file.txt", dtype=int).tolist()
