py3在input控制台怎么循环5个回车？

Question

f.write(line + '''
        ''')

原代码

line = input()
while line:
    with open('test.txt','a') as f:
        f.write(line + '''
        ''')
    line = input()

Answer 1

是不是每次运行追加5行数据？
以下代码，过虑了空行，回车前有内容才计1次，5次后退出

count = 0
while count<5:
    line = input()
    if line: #判断空行，不要排除空行就去掉
        with open('test.txt','a') as f:
                f.write(line + '\n')
                count += 1
