今天弄了一个晚上没弄出来一个小东西，只弄出来了写追加，而且还是笨方法，起码死不掉那种。

现有txt配置文件

具体就是最好一项backend的修改、追加、删除，只弄出来追加，下次再填坑。

具体代码如下

#增加
def add(a,b,c,d):
    backend_new = open('haproxy','a+')
    backend_new = backend_new.write('backend %s\n\t\tserver %s weight %s maxconn %s'%(a,b,c,d))

add(
        a = input('1.输入backend:'),
        b = input('2.输入server:'),
        c = input('3.输入weight:'),
        d = input('4.输入maxconn:')
)

本来还以为def发现新大陆....
