一：逐步进行操作：
1.查询功能：
当用户输入www.oldboy1.org用户信息后，打印对应的server信息：
server 10.10.0.10 10.10.0.10 weight 9999 maxconn 33333333333
server 10.10.10.1 10.10.10.1 weight 22 maxconn 2000
server 2.2.2.4 2.2.2.4 weight 20 maxconn 3000
while 1:
l=[]
flag=1
m=input("please input your choise:").strip()
with open("test",encoding="utf8") as f:
for i in f:
if i.startswith("backend") and m in i:
flag=0
continue
if i.startswith("backend") and flag==0:
break
if flag==0:
l.append(i)
for p in l:
print(p.strip())
2.增加功能：
当用户输入｛"backend":"www.oldboy20.org","record":{"server":1111,"weight":2222,"maxconn":3333}｝
在www.oldboy20.org下增加一条server信息，即文件中：
backend www.oldboy20.org
server 10.10.0.10 10.10.0.10 weight 9999 maxconn 33333333333
server 11111 weight 2222 maxconn 3333
while 1:
a=input("please input your choise:".strip())
dic=eval(a)
b=dic["backend"]
c=dic["record"]
flag=1
l=[]
s="\t\tserver %s weight %s maxconn %s \n" %(c["server"],c["weight"], c["maxconn"])
with open("haproxy.conf", encoding="utf-8") as f, open("test", "w", encoding="utf-8") as w:
for line in f:
w.write(line)
if line.startswith("backend") and b in line:
flag=0
continue
if line.startswith("backend") and b not in line and flag==0:
flag=1
continue
if flag==0:
l.append(s)
for line1 in l:
w.write(line1)
import os
os.rename("haproxy.conf","conf_bak")
os.rename("test","haproxy.conf")
os.remove("conf_bak")
3.删除功能
当用户输入｛"backend":"www.oldboy20.org","record":{"server":1111,"weight":2222,"maxconn":3333}｝
会将www.oldboy20.org下的server 11111 weight 2222 maxconn 3333删除，
在文件中如下：
backend www.oldboy20.org
server 10.10.0.10 10.10.0.10 weight 9999 maxconn 33333333333
while 1:
a=input("please input your choise:".strip())
dic=eval(a)
b=dic["backend"]
c=dic["record"]
flag=1
s="\t\tserver %s weight %s maxconn %s \n" %(c["server"],c["weight"], c["maxconn"])
with open("haproxy.conf", encoding="utf-8") as f, open("test", "w", encoding="utf-8") as w:
for line in f:
if line.startswith("backend") and b in line:
flag=0
if line.strip()==s.strip() and flag==0:
flag=1
continue
w.write(line)
import os
os.rename("haproxy.conf","conf_bak")
os.rename("test","haproxy.conf")
os.remove("conf_bak")
4.修改功能：
当用户输入｛"backend":"www.oldboy2.org","record":{"server":0000,"weight":0000,"maxconn":0000}｝
在文件中如下：
backend www.oldboy2.org
server 0000 weight 0000 maxconn 0000
while 1:
a=input("please input your choise:".strip())
dic=eval(a)
b=dic["backend"]
c=dic["record"]
flag=1
s="\t\tserver %s weight %s maxconn %s \n" %(c["server"],c["weight"], c["maxconn"])
with open("haproxy.conf", encoding="utf-8") as f, open("test", "w", encoding="utf-8") as w:
for line in f:
if line.startswith("backend") and b in line:
w.write(line)
flag=0
continue
if flag==0:
flag=1
line=s
w.write(line)
import os
os.rename("haproxy.conf","conf_bak")
os.rename("test","haproxy.conf")
os.remove("conf_bak")
二：合并成函数：
虽然功能可以简单的实现，不过感觉很烂。。。

l=[]
flag=1

for i in f:

for p in l:
print(p.strip())
