拆分函数返回意外结果

Question

我有一个文件，有多行数据用逗号分隔，如

Mary,F,6919
Anna,F,2698
Emma,F,2034
Elizabeth,F,1852
Margaret,F,1658
Minnie,F,1653

我正在阅读文本文件并尝试拆分单词

filename = 1880.txt
with open(filename) as f:
    content = f.readlines()
content = [x.split() for x in content]

它将结果显示为

['Mary,F,9889', 'Anna,F,4283', 'Emma,F,2764', 'Elizabeth,F,2680', 'Minnie,F,2372']

我希望内容变量应返回每行，数据以逗号分隔，如

[('Mary','F','9889'), ('Anna','F','4283'), ('Emma','F','2764'), ('Elizabeth','F','2680'), ('Minnie,'F','2372')]

我使用拆分功能的错误在哪里？

Answer 1

答案应该是

filename = 1880.txt
with open(filename) as f:
content = f.readlines()
    content = [x.strip().split(',') for x in content]

Answer 2

您可以迭代文件对象一次，应用str.strip删除尾随'\n'：

new_data = [tuple(i.strip('\n').split(',')) for i in open('filename.txt')]
