import csv

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

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

import csv

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

我认为这是最好的选择。

temp = [line.strip() for line in file.readlines()]

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() 

试试这个:

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