用Python将一行数字读入列表

我试图将文件中的两行读入两个列表，这样每一行都在一个列表中

data.txt：

1,5,7,18,9,8,12
2,41,12,11,1,10

我尝试过的代码：

list1 = []
list2 = []
infile = open("data.txt","r")
line = infile.readline()
for line in infile:
    line = line.split(',')
    list1.append(float(line))
    line = infile.readline()
    list2.append(float(line))
    print(list1)
    print(list2)
print()

list1 = [1, 5, 7, 18, 9, 8, 12]
list2 = [2, 41, 12, 11, 1, 10]

我想要的：

list1 = []
list2 = []
infile = open("data.txt","r")
line = infile.readline()
for line in infile:
    line = line.split(',')
    list1.append(float(line))
    line = infile.readline()
    list2.append(float(line))
    print(list1)
    print(list2)
print()

list1 = [1, 5, 7, 18, 9, 8, 12]
list2 = [2, 41, 12, 11, 1, 10]

如何修复我的代码？

您的代码中有许多错误，因此我将发布一个更好的方法：

with open('data.txt', 'r') as file:
    list1 = [int(number) for number in file.readline().split(',')]
    list2 = [int(number) for number in file.readline().split(',')]

print(list1)
print(list2)

输出：

[1, 5, 7, 18, 9, 8, 12]
[2, 41, 12, 11, 1, 10]

[1, 5, 7, 18, 9, 8, 12]
[2, 41, 12, 11, 1, 10]

您也可以在一行中完成：

list1, list2 = [[int(n) for n in line.split(',')] for line in open('data.txt').readlines()]

你有什么错误吗？什么是你的Quy？你几乎在那里，但考虑有列表[0 ]和列表[1 ]而不是List1和List2。因此，一个2D列表，其中第一个dim给出行，第二个索引行。你能发布你的data.txt吗？你有任何错误吗？什么是你的Quy？你几乎在那里，但考虑有列表[0 ]和列表[1 ]而不是List1和List2。因此，一个2D列表，其中第一个dim给出行，第二个索引行。你能发布你的data.txt吗？
