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。

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 server %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....
