python从txt文件中读取数字，并放入list中 用Python读取文件中的数字并加入list的问题
python \u4ecetxt\u4e2d\u8bfb\u53d6\u6570\u636e\u5230 list \u4e2dlist1,list2,list3.... \u6709\u591a\u5c11\u884c\u4e8b\u5148\u77e5\u9053\uff1f
a = open('myfile.txt')lines = a.readlines()lists = []#\u76f4\u63a5\u7528\u4e00\u4e2a\u6570\u7ec4\u5b58\u8d77\u6765\u5c31\u597d\u4e86for line in lines: lists.append(line.split())print(lists)
array = []for line in open('testdata.txt'): array.extend(line.strip().split(' '))array = map(int, array)print(array)
背景：
文件内容每一行是由N个单一数字组成的，每个数字之间由制表符区分，比如：
0 4 3 1 2
2 1 0 3
1 2 0
……
现在需要将每一行数据存为一个list，然后所有行组成一个大的list。
工具：
1.strip()：用于移除字符串头尾指定的字符，默认为空格，返回是字符串。
2.split()：通过指定分隔符对字符串进行切片，返回是字符串组成的list。
