temp = open(filename,'r').read().splitlines()

试试这个:

u=open("url.txt","r")  
url=u.read().replace('\n','')  
print(url)  

temp = open(filename,'r').read().split('\n')

my_file = open("first_file.txt", "r")
for line in my_file.readlines():
    if line[-1:] == "\n":
        print(line[:-1])
    else:
        print(line)
my_file.close() 

这个脚本将从文件中提取行，并将每一行不带换行符的行保存在file2中。

file = open("temp.txt", "+r")
file2 = open("res.txt", "+w")
for line in file:
    file2.writelines(f"{line.splitlines()[0]},0\n")
file2.close()

如果你看line，这个值是data\n，所以我们输入splitlines()

要使它作为一个数组和[0]选择唯一的字数据

import csv

with open(filename) as f:
    csvreader = csv.reader(f)
    for line in csvreader:
         print(line[0])
