由于你的内容已经包含你想要的换行符，所以通过使用可选的end参数告诉print()函数不要添加任何内容：

def print_one_line(line_number,f):
    print(line_number,f.readline(), end='')

而不是跳过输出的换行符，您可以从输入中去除它：

print(line_number, f.readline().rstrip('n'))

Beside the other ways, you could also use:

import sys
sys.stdout.write(f.readline())

Works with every Python version to date.
