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() 

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()]

要去除尾随的行结束符(/n)字符和空列表值(")，尝试:

f = open(path_sample, "r")
lines = [line.rstrip('\n') for line in f.readlines() if line.strip() != '']

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