从文本文件python中读取 [英] Reading from a text file python

问题描述

我有一个包含数字矩阵的文本文件:

I have a text file which contains a matrix of numbers:

999 999  10  8
3 4 999 999 999 
6 999 2 7 999
999 6 3 5  6
999 9 1 10 999
10 6 999 2 2 999

我正在尝试读取每一行并将其存储到 Python 中的数组中，但是我无法将每个值从 string 更改为 int.我在解析每一行时尝试使用 int() 但我得到了无法将 list 传递到 int() 参数的错误.

I'm trying to read each line and store it into an array in Python but I'm having trouble changing each value into an int from a string. I tried using the int() when parsing each line but I get the error of not being able to pass list into the int() argument.

推荐答案

试试看:

matrix = [[int(i) for i in line.split()] for line in open('myfile.txt')]

如果您不想要第一行，请先阅读它.

[edit] if you don't want the first line just read it before.

with open('myfile') as f:
    f.readline()
    matrix = ....
